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.

Failing Fuel Pumps: 3 Signs And Symptoms To Watch Out For

Diesel engines are quite popular in the United States; approximately 10 diesel trucks are sold for every 100 trucks sold. They’re primarily relied upon for their exceptional highway mileage rating and stellar efficiency.

That being said, any vehicle is only as good as its parts; if one piece of the puzzle is damaged or broken, the entire structure will fail. Diesel fuel pumps play a major role in these efficient engines and can cause significant problems in diesel fuel systems if they malfunction or break down. Let’s take a look at three signs that indicate a failing diesel fuel lift pump.

  1. The engine stalls. Many people believe that they have run out of gas or that there is an issue with their gas gauge when they find themselves sitting on the side of the road with a stalled engine. While that is certainly a possibility, don’t rule out the fuel pump; if it quits working, the fuel injectors will not have any fuel to pump and no internal combustion will occur.
  2. The engine overheats. This not-so-obvious indicator occurs when the fuel pump is heated frequently as a result of stop-and-go driving patterns. It overheats, causing the engine to overheat as well. If you let the engine cool down until it functions properly again, only to overheat once more, your fuel pump is most likely responsible.
  3. You’re hearing weird noises. Unusual noises are always a worry when they’re coming from under your hood. If the flow to the fuel injection system is not consistent, you may experience hesitant starts and take-offs as well as sputtering or backfiring. Of course, the only way to tell for sure that your fuel pump is the culprit is to take your vehicle to a mechanic for a professional diagnosis.

Maintaining the health of your diesel engine means caring for each part of its fuel system. Diesel fuel systems possess many components, each of which could fail and cause further (costly) damage to the rest of the vehicle. By keeping an eye out for the above symptoms of a failing fuel pump, you can rest assured that at least one of these components is doing its job.

Basics of Diesel Engine Fuel Systems

The average diesel engine can get somewhere between 400 and 800 miles per tank. But if the filtration system has a fail-point, the system becomes inefficient. Diesel engines are efficient, but it’s also important to understand how the system works to keep the vehicles running at their peak efficiency. Here are the typical components of a diesel filtration system and overall fuel system.

Diesel Fuel Filters

Diesel fuel filters (i.e. full-flow filters) are used to filter diesel fuel several times in the system. The filters help keep particles out of the system that can build up over time and cause efficiency issues with the engine.

Fuel filters are used in any fuel system, but they’re especially important for diesel systems. The reason for this is that diesel fuel is more viscous, and the extra potential for buildup in the system leaves the engine more susceptible to damage. Regularly changing the filters and routine maintenance of the diesel filtration system will help keep the engine running smoothly.

Diesel Fuel Transfer Pump

While a basic fuel system can rely on normal air pressure to distribute fuel throughout the system, a modern diesel system requires a fuel transfer pump. The pump allows fuel to be transferred to the fuel injection system.

Sometimes, an aftermarket lift pump can be installed to increase to improve the fuel system and maintain an optimal PSI for the fuel pressure to ensure long-lasting high performance.

Fuel Air Separation System (FASS)

Combing the lift pump and the filtration system, the FASS combines both into an effective mechanism that helps improve fuel efficiency for diesel engines.

The separation systems are compact and have high-performance fuel pumps that increase longevity and lifespan of the diesel engine’s fuel injection system.


Diesel engines are powerful and efficient combustion engines. But, complex and powerful modern engines require extra filtration and more power than a simple engine. With multiple steps in the filtration process, quality fuel filters are extremely important. And, it’s also important to have a high-performing pump to ensure that the proper fuel pressure is maintained for performance. A combination fuel air separation system can help extend the life of a fuel injection system and improve fuel efficiency. When properly maintained with the best working parts, fuel and filtration systems can last a long time and allow diesel engines to run smoothly.

Fuel Filters For The Needs of Today’s Cars and Trucks

Fuel filters are a vital part of the proper functioning of an automobile. They filter out dirt, dust, grime, and other impurities from entering the combustion chamber. Like the Princess and the Pea, fuel systems are quite sensitive and even the smallest of particles can wreak havoc on today’s technologically fine tuned engines. Fuel filters should be changed approximately 25,000 to 30,000 miles, depending on driving conditions. If you drive in a dusty, smoggy, and/or hot environment, your car will need a fuel filter change sooner than a car that only drives in relatively mild and clear conditions. Fuel filter manufacturers design fuel filters for the needs of today’s cars and trucks.

There are at least two main benefits to driving with a clean fuel filter. We will examine these benefits next.

Driving With A Clean Fuel Filter Will Give Your Car Optimal Performance

  • Optimal performance. A clean fuel filter allows your car to run in peak condition. Today’s technologically advanced engines are affected negatively even by slight variances in conditions and foreign objects in its systems. A clean fuel filter keeps the fuel system working properly and at maximum efficiency.
  • A clean fuel filter filters out impurities, which keeps the car’s fuel injection system primed to deliver the cleanest, most precise amount of fuel needed for the engine’s needs during the idling and driving experience. Clean fuel filters keep impurities such as water, dirt, rust, and particulate matter from disrupting engine performance.

A clogged fuel filter prevents the fuel system and engine from running at peak performance. Therefore, you should be aware of the symptoms of a clogged fuel filter.

A clogged fuel filter makes the fuel pump worker harder and less efficiently. Under more demanding driving conditions, for example, your car is loaded with more weight, is pulling something or driving on an incline, you will notice that your car’s engine is not getting the “juice” it needs to compensate for these demands.

Additionally, a clogged fuel filter will prevent your car from starting quickly or at all. Acceleration, even under normal driving conditions, may be hindered. This can be dangerous when acceleration is most needed. Imagine you are merging onto a freeway and there is a tractor trailer coming up behind you in your lane. You will want your car to accelerate quickly so that you can get in front of the lumbering truck, especially if there is not room to slow down and wait for the big rig to pass.

Also, a clogged fuel filter will cause your car to not idle properly, which can cause problems when yielding and stopping. You do not want your car to die, either when decelerating or at a full stop. Moreover, the misfires that can happen from clogged fuel filters will negatively affect your car’s performance at any point during the driving experience.

Be sure to have your car’s fuel filter changed regularly.

Fuel filter manufacturers design today’s fuel filters to deliver the peak performance your car needs.
