Red, black, white and yellow trucks diesel fuel polishing


You’ve been in the over the road trucking industry long enough to know that being an owner-operator takes a lot of business savvy to manage your load schedule, seat time, maintenance costs, and other business expenses required to keep your trucking business up and running. Diesel fuel polishing might sound strange to you but as an owner-operator did you know that down time resulting from lengthy and costly maintenance to your rig affects operation cost per mile and ultimately your bottom line? Diesel engine performance and specifically how diesel fuel is polished on the way through your fuel system is an important aspect of your rigs health and road worthiness.


Did you know that when fuel passes through the stock filter, it breaks large air bubbles into smaller ones that eventually still get through and reach your injection components? With air in the injector tip, there is no fluid damping, which allows the plunger to impact the tip with up to 50% greater force which leads to cracked injector tips or even worse, tips that are broken off into the cylinder. Plus, the presence of air reduces lubrication by at least 10% which causes galling and scoring. When combined with higher pressure in fuel, the injector orifice is exposed to a cutting torch effect which can damage your injectors even more. That’s where the FASS fuel system comes in and the diesel fuel polishing it provides.


The FASS process begins way ahead of conventional fuel systems and removes dirt and debris before fuel enters the electric fuel pump.  Next, fuel enters the high efficiency Extreme Water Separator. Here, FASS traps and removes 99.96% of water molecules and continuously polishes the fuel.  Air and vapor are then returned back to your fuel tank and exclusive performance radius cuts in the FASS system create the smoothest path to your injectors. The mass flow return continually polishes the fuel making FASS second to none in regards to achieving the cleanest possible fuel being delivered to your engine, period!


By delivering pure polished fuel without contaminants, FASS creates a longer, cleaner burn, and the proper atomization of fuel across the piston reduces regens. The FASS Titanium Signature Series fuel system continuously polishes diesel fuel and removes water, dirt, air and vapor contaminants to lower maintenance cost, increase mileage performance, reduce regens, and improve power and torque vital for hauling big and sometimes ugly loads cross country.  So, before you get up and go out for another week of hauling freight across country let an authorized FASS dealer review your rig specs and find the right FASS fuel system solution for you.

black, grey, red, and white trucks in snow diesel fuel gelling prevention tips


As the calendar pages turn towards December and the colder winter months, it’s time to talk about diesel fuel gelling prevention tips and how a FASS system can help with this problem. Diesel fuel contains paraffin and will solidify and gel when the temperature drops. At 32 degrees Fahrenheit the paraffin in diesel crystalizes and becomes cloudy.  When it really gets cold, in the 10-15 degrees Fahrenheit range then the paraffin will gel and cause clogged fuel lines and filters. Some signs that your diesel fuel could be gelling in cold weather can be the engine not starting, sluggish throttle response, improper acceleration, and marked differences in fuel pressure indicators.



How to prevent diesel fuel gelling?  Before answering this question, first let’s examine what type of diesel fuel you are putting in your truck. Diesel fuel at the pump is typically offered in #1 or #2 varieties. What’s the difference?  #1 diesel fuel generally has lower energy components and also has paraffin removed from the chemical mix. The absence of paraffin means that #1 diesel fuel will not gel in colder weather and is generally more liquid and has less viscosity than #2. On the other hand, #2 diesel fuel is what is most commonly found at the pump and is slightly more viscous than #1 and burns more slowly which increases fuel mileage. In the colder winter months, many truck drivers turn to a mixture of #1 and #2 diesel to combat the effects of fuel gelling in colder weather.


Adding an additive fuel treatment is another diesel fuel gelling prevention tip, as they combat the gelling effect by preventing crystals from forming in the paraffin. Other diesel fuel gelling prevention tips include idling the engine at all times to keep the fuel warm to prevent gelling. Although idling is effective, it is not recommended due to the lowering of fuel economy and wear and tear it produces on the engine.



Here at FASS, customers have an easy built-in solution to our fuel air separation systems to prevent diesel fuel from gelling in cold weather. Customers who purchase our Titanium Signature Series fuel air separation systems get two built in electric heater ports that provide easy installation of our electric heater kit.  Each electric heater kit provides a heating element that produces 100 watts of electric heat to warm cloudy or gelled diesel fuel. When installed, the heater will begin warming the diesel fuel once the key is in the on position and will automatically shut off after the proper fuel temperature has been reached. FASS recommends customers install 2 of the electric heater kits if you are running in temperatures below minus 20 degrees Fahrenheit whereas otherwise one electric heater kit should suffice.


Or, another newer option that we’re offering customers is our High Output Fuel Heater Disk that automatically powers on when the temperature drops below 34 degrees Fahrenheit to counter the gelling effect. The powerful heating element in the High Output Fuel Heater Disk provides 300 watts of electric heat to warm gelled diesel fuel and ensure your rig is running at optimum performance. We have tested our electric heater kit’s starting performance with #2 diesel fuel down to minus 30 degrees Fahrenheit and have run at -40 degrees Fahrenheit!  FASS simply can’t be beat in cold weather performance and FASS is committed to keeping you running even in the coldest weather conditions!


It’s that time of year again…you know the annual Specialty Equipment Market Association or more popularly known SEMA show kicks off this week in Las Vegas. SEMA is the annual product showcase for the automotive aftermarket parts trade and is also a great opportunity for truck manufacturers to roll out some really cool concept builds and upcoming model updates. For example, at this year’s SEMA dealers can get a glimpse of Ford’s all new 2020 Super Duty truck series which will debut at the end of this month. Ford will offer the Super Duty in a brand-new Tremor series which is an off-road trim package that includes a concealed winch in the bumper, 2 inch lift, locking rear differential and Goodyear Wrangler Duratrac tires. One of the custom diesel truck builds BDS Suspension is bringing to SEMA is the Ford F-350 Super Duty Crew Cab XLT Overlanding model. This 6.7-liter Power Stroke diesel V8 powered overlanding machine comes equipped with a 4-inch radius-arm suspension lift and Fox springs and shocks that help steer the ginormous 40-inch-diameter Mickey Thompson tires. Overlanding amenities for this beast also include a refrigerator and power inverter to drive juice to needed accessories as well as being outfitted with an air compressor, gas grille with two burners, and a tent for sleeping on top.


Not to be outdone by Ford, Dodge will also bring several innovative builds to SEMA not the least of which is the MOPAR Ram 1500 Rebel OTG (Off the Grid). Dodge’s overlanding submission is powered by a 3.0-liter V-6 EcoDiesel engine that delivers precision torque and grip. A rooftop tent anyone to go along with your diesel power train? This Dodge has got that and more with a collapsible awning and rear mounted propane tank for the gas powered stove and a Dometic refrigerator to keep your vittles fresh. The bumper has a 10,000 pound Warn Winch and four high-power LED off-road lights. Extended range for overlanding is provided through the 33-gallon capacity fuel tank (increased from 26-gallon standard capacity).  A two-inch lift kit and Goodyear MT/R Kevlar tires give this Dodge beast the necessary equipment for serious off-roading.


At FASS, we especially applaud the two diesel offerings and remember, FASS is committed to your dealer satisfaction and providing the best fuel air separation system solutions for your diesel truck and we hope to see you at the SEMA show!


Whether you just drove your new dream diesel truck off the dealership lot or bought a used work truck from a Craigslist posting, we should first talk about adequate fuel filtration and how important it is to your engine and fuel system’s longevity. Diesel pickup and class 8 trucks have seen some important changes in their fuel injection systems over the past 10-20 years.  Increasingly, modern high-pressure common rail systems (HPCR) operate at pressures in the range or excess of 30,000 psi. Fuel injectors that are operating under these high pressures have much tighter tolerances and can be affected by the slightest contamination of fuel either by air bubbles, dirt, water, bacteria, or any other unwanted particles entering the fuel stream.


Modern diesel fuel injectors have smaller diameter nozzle openings where the fuel is squirted through into the combustion chamber. Any air or particle contamination in the fuel can cause the injector timing to become faulty, cause the blocking of nozzles, induce altered spray patterns, or worse reduce the fluid dampening effect of diesel fuel and create conditions for injector failure. As air and vapor enter the injector orifices at increased pressures and cause uneven orifice openings it creates a cutting torch effect which damages your injectors and throws of their timing and efficiency resulting in lost horsepower/torque. Fuel injection is designed to inject a predetermined amount of fuel at a predetermined time. Air occupies space in the fuel and changes the amount of fuel being delivered which retards injection timing and can also result in lower gas mileage in addition to reduced horsepower and torque.


Here at FASS, we offer a dedicated diesel fuel air, water, and particle separation system that will deliver the purest and cleanest fuel to your engine. A FASS fuel air separation system works by removing air and vapor which will create a more complete combustion event and produce an increase in horsepower/torque and improve your gas mileage. So, if you are looking to increase the longevity of your trucks diesel engine and fuel filtration system give us a call at 1-866-769-3747 and let us help you improve your diesel trucks fuel system performance!

Diesel Truck Repair Projects You Can Do Yourself and 3 You Can’t

Sure, everyone loves a good deal. This is why many people often resort to do-it-yourself projects when they first see signs of trouble with their vehicles. However, since not many people are experts in the automobile industry, they could end up doing more harm than good. Whether you’re an everyday driver or mechanic, it’s important to emphasize what can be done in the comfort of your own home, and what can’t.

Here are a few truck maintenance issues you can solve yourself, and others you need an expert in the field to take a look at.

Truck maintenance

Maintaining the vehicle is something that should be expected of the driver. For every 100 cars sold, only 10 are powered by a diesel engine—making them the minority. So, it’s especially important to maintain the vehicle and keep it in the best shape possible to prevent serious damage.

Stop algae right in its tracks

Before we jump into replacing diesel fuel filters and diesel fuel pumps, it’s important to note that one of the best things you can do to maintain your engine is to eliminate mold and algae.

Drain any excess water from the engine, or make sure you are using biocide to treat the engine and rid yourself of growing fungi.

Replace the diesel fuel pump

This is something else you can do from home as long as you have the right parts like a fass replacement pump or fass fuel pump.

Signs that you may need a new fass replacement pump include:

  • struggling to accelerate
  • engine breakdowns
  • low gas consistently

A fass replacement pump can change the game, and have anyone driving down the road like they just purchased a brand new vehicle.

Change the fuel filters

Changing the fuel filters is another task that does not require an expert. This should be done every six months to a year for optimum performance.

Issues that require an expert

However issues that require an expert in the field include:

  • issues with your brakes
  • issues with a severely damaged part
  • wheel alignments and tire rotations

Though there are a few projects you can take the liberty of doing yourself, these big ticket issues require someone with professional experience.

Maintenance versus a severe issue

There are very few issues the everyday driver can handle on their own. Unless they’ve had experience or have diligently studied the complicated makeup of a diesel truck’s engine—it’s best to leave the complicated issues with the pros.

Though it can be tempting to take the reigns, it’s best to stick with performing routine maintenance on the vehicle yourself instead.

Is Your Diesel Fuel Pump Damaged? Find Out Below

Diesel engines are very popular around the world because they are powerful enough to drive heavy machines. Most of the European countries have a strong affinity for diesel engines than petrol engines. For instance, 96% of commercial vehicles in the United Kingdom are powered by diesel.

Just like in petrol, diesel engines experience mechanical problems in the diesel filtration system and around the fuel pump. Chances of a diesel fuel pump malfunctioning are higher because it takes much more effort to combust diesel than petrol. If you own a diesel engine powered vehicle, here are some simple warnings that your diesel fuel pump may need replacement.

1. High-Pitched Sound

It is common for vehicles to produce sound when they start or when they are accelerating. However, the sound produced by your vehicle should not turn heads. If your vehicle is making high-pitched sound, just know that there is something wrong with the diesel fuel pump. If you hear your vehicle make unusual or scraping sounds, it is high time you replace the entire diesel fuel supply system.

2. Low Fuel Pressure

Thousands of diesel-fueled vehicle owners have experienced this problem, but they fail to understand what is wrong with their vehicles. Most of them have a feeling that it has something to do with fuel contamination. However, if your diesel fuel pump is not working properly, there is a high chance that there will be low fuel pressure. The rest of the parts within the pump system will be functioning normally, but your vehicle will have trouble starting.

3. Malfunctioning Fuel Filters

Diesel fuel filters tend to wear out within a short period. All people using diesel engines are well aware that they will have to keep replacing their diesel filtration system regularly so that they can keep their engines functioning as expected. However, sometimes your filtration system might be wearing out within a day or two, which is suspicious. If you’re experiencing such situations, you have a problem with diesel fuel transfer pump, and it needs to be replaced.

4. Acceleration Problems

Many people, especially those with very little knowledge about their fuel system attribute acceleration problems to engine failure. However, engine failure has nothing to do with acceleration or deceleration of your vehicle. The problem emanates from your fuel pump. If your diesel fuel pump has been damaged and does not have sufficient power to draw enough diesel to the combustion tubes, there is a high chance that your vehicle will fail to accelerate. In such situations, you need to replace your fuel pump.

5. Sudden Stops

Sudden stops seem to be a common occurrence with diesel vehicles. There is no doubt that you have, on several occasions, come across a truck or heavy earth-moving machine on the roadside after experiencing sudden stops. You might have concluded that it is a problem with older automobiles, but new cars are also experiencing the same problem. If your diesel engine suddenly stops, you should know that the diesel fuel pump is damaged. It is not supplying sufficient diesel to the combustion system due to low pressure.

6. Engine Breakdowns

The scariest matter about your car is getting to know that you have an engine breakdown. Sometimes it could be a minor problem, but in other cases, you could find yourself on an extreme edge where you have to replace your engine. Diesel fuel transfer pumps play a significant role in the breakdown of your engine. Low pressure and failure to supply sufficient fuel to the engine systems lead to severe damages.

If your diesel system has been exhibiting these signs, you need to have it replaced within the shortest time possible before the situation gets worse. FASS Diesel Fuel Systems have the solution to your damaged fuel pump, and they will provide immediate and reliable replacement services.


The summer truck sales figures are out and it looks like Dodge Ram is gaining on its’s main rivals Ford and GM.  Long a distant third place contender to Ford and GM, Dodge Ram is starting to turn heads with its newly upgraded pickup truck line and improved sales figures.  A newly redesigned fifth generation Ram 1500 series is leading the way for Dodge in its Ram pickup truck category line.  Offered with an available EcoDiesel V6 engine, the 1500 series has something for the diesel truck enthusiast looking for added torque and gas mileage savings a diesel powertrain provides. So far, the numbers point to Dodge overtaking Chevrolet as the #2 sold truck brand, however it still lags GM when factoring in GMC truck sales into the Chevrolet numbers.


Dodge has partially gained a leg up on Ford and GMC by offering sleeker interiors and a redesigned Apple iPad inspired 12 inch touch screen in the center console offered in its Ram 1500 series.  Yes, torque, hauling capacity, and other traditional diesel truck features are still important but now, more digitally connected buyers are looking for connectivity features for their smart phones as well as enhanced navigation and other system control features like oil pressure and engine temperature monitoring.


For Dodge, the proof is in the pudding in its sales figures which show through May Dodge Ram’s share of the truck market rose 4 percentage points to just over 24%.  Although much of the gains in Ram’s market share are attributed to the lower price 1500 Classic model there is a lot to be proud of in Ram’s larger diesel capable 2500 and 3500 series.  Here at FASS, we offer a full range of diesel fuel filter systems for your Dodge Ram diesel truck.

Your Diesel Filtration System Is More Important Than You Think

Your diesel filtration system has a very important job. Every part of the system is tasked with ensuring the bad stuff does not make it to the engine and cause it to lock up. Taking care of your diesel filtration system is a great way to take care of your diesel motor.

One of the most important parts of any diesel filtration system is the diesel fuel filters. The filters are the main part of the system. High-quality diesel fuel filters get the job done nicely.

What is the Main Job of the Diesel Filtration System?

Diesel fuel systems are one of the most vital parts of a diesel engine. The right filtration system ensures that debris like rust, scale, and dirt do not get into the engine and they also keep water out as well. These impurities can wreak havoc on a diesel engine.

Diesel fuel supply system configurations include typically two filter points. Diesel fuel filters are full-flow filters. All the fuel has to go through the filtration system to ensure that the fuel does not contain contaminants before it reaches the injector.

Your Fuel System

Diesel engines are reliant on precise fuel injection to operate. Unlike gasoline engines, they do not rely on a spark for combustion. Diesel engines rely on hot air and precision measurement of the fuel injectors. The fuel system includes:

  • Fuel tank
  • Fuel lines
  • Fuel filtration system
  • Fuel pumps
  • Fuel injectors

Each part of the process is vital to your engine running at its optimal. The filtration system plays a key role in your engine delivering the energy efficiency and reliability that you expect.

Fuel Lines Are The Easy Part

Typically the lines from the fuel tank never fail unless they are exposed to extreme conditions. Rarely do fuel lines have to be replaced if regular general maintenance is carried out.

Universal Fuel Pumps

Diesel fuel pumps can fail especially when the filtration system is not maintained as recommended. Many drivers choose universal fuel pumps because they are easier to maintain (parts are more available) and deliver a sure level of reliability.

Fuel Injectors

Diesel fuel injectors are another part that can fail if the filtration system is not maintained regularly. If debris makes it to the injector heads there is a good possibility that the engine will not turn over.

The Bottom Line

Most fuel line issues can be prevented with regular filtration system maintenance. Turn to a trusted supplier for your fuel system needs and get the parts you can depend on.

The Importance of Using the Right Diesel Fuel Filter Supplier

When it comes to finding the right supplier for your diesel fuel filters, there can be a number of different hurdles. You want to be sure that you are getting the best parts that last and provide quality, while also staying within the limits of your budget. With a wide range of different suppliers available to wholesale distributors and consumers alike, it is hard to know which ones are worth your time, and which ones you are better off ignoring. By educating yourself about the different options available to you, you will be much better prepared when it comes time to make a final choice for your diesel fuel filters. If you follow our simple guide below, you will that much closer to finding all the best parts to meet your professional goals. Let’s get started.

What attributes should I look for in a diesel fuel filters supplier?

To begin, it helps to have some basic knowledge about the state of diesel fuel filters in the current day. Understanding where a supplier’s interests lie helps you to determine how to find the best deal, while also ensuring quality. Most diesel fuel filters suppliers have a number of guidelines that they have to abide by. This means that while their products can ensure compliance with standards, they may have to adjust prices depending on the nature of your specific industry, the volume you are requesting, and your location. When you consider these factors, you may have some more clarity on why certain suppliers behave the way they do. It is perhaps always your best bet to establish a strong, ongoing relationship with a single supplier so that you can build trust and reduce friction when it comes to getting accurate, timely orders filled.

Of course, the type of diesel fuel systems that you are looking to provide parts for will have an impact on the diesel filter manufacturers you choose. Take, for example, the baseline consideration of fuel injection pressures. To maximize the chances of combustion, fuel injection pressures begin extremely high, ranging from 30,000 psi or more, to force fuel into tiny droplets and increase the surface area of the fuel. Taking these technical processes into consideration will help you when you are looking for a supplier to provide you with the right diesel fuel filters.

How should I choose a supplier for my diesel fuel filters?

It is always a wise move to look for suppliers that have demonstrated experience in the field as a whole. What this means for you is that you should always be able to establish a supplier’s credentials. Sometime you may have to ask questions, but any dependable supplier will be happy to address your concerns in order to ease your mind. For example, it is prudent to ask them about their experience with companies in similar industries to yours. You may also find it helpful to ask how much experience they have with diverse diesel filtration systems. Of course, more obvious indicators of legitimacy, such as certifications, licenses, and insurance are a good thing to ask about, too.

Asking trusted colleagues, peers, and members of your industry community may also help to lead you in the right direction. Often times a supplier’s worth is proven in the testimonies of its past customers. Finding a supplier that values the opinions of their clients helps to establish long lasting, trusting relationships that can weather all kinds of market conditions. When you know you can put faith into your supplier, it becomes much easier to do business with them over many years. The combination of industry knowledge and excellent customer service cannot be overlooked when it comes to diesel fuel filter suppliers.

While finding a new supplier for your diesel fuel filters can present a unique set of challenges and obstacles, it is an important part of doing business in today’s world. If you are looking for a reliable supplier of diesel fuel filters with years of experience and specialized, industry specific knowledge, then do not hesitate to contact us today. We would love to supply you with the right diesel fuel filters for all your needs, big and small.


Overland trucking puts a lot of wear and tear on your fuel injection system. Water, dirt, air, and vapor gradually accumulate and entrain causing decreases in fuel delivery performance that ultimately affect your fuel mileage. Your stock fuel filter can only do so much to compensate for the buildup of entrained air and vapor as well as excess dirt and other particulates that accumulate over time in your fuel tanks. Luckily, there is a better way to filter and improve your fuel system’s performance.  The FASS Titanium Signature Series fuel system has a filtration rating of 2 microns which is far superior to your stock factory filter and helps improve your overland fuel mileage which can impact your bottom line.


How much can a FASS Titanium Signature Series fuel system improve your mileage performance?
