3 Winter Tips To Keep Your Diesel Engine Running Smoothly In Frigid Temps

For many people, their cars are like their children. And just like with children, you need to keep them safe when the weather turns cold and the snow starts to fall. Though your diesel vehicle may not suffer from frostbite, there are a number of weather-related damage that could occur if you don’t prepare for it ahead time. We may be in the thick of this frigid season, but it’s never too late to take the proper precautions to safeguard the health of your diesel engine. Here are three ways to do just that.

  • Test your batteries: Just like any other car, testing your batteries to make sure they can handle the added strain of colder temperatures can ensure you don’t get stranded. The average car battery lasts between two and five years; if yours is getting on in age (or you can’t remember how long you’ve had it) testing it is the best way to see if it’ll make it through winter.
  • Use an anti-gel additive: Diesel fuel systems are a vital component of your vehicle. In severe cold, diesel fuel can reach its cloud point (the measure of diesel’s low-temperature operability) and begin to thicken and gel up. Most diesel fuels do this between 20 and -18 degrees Fahrenheit. By including a fuel additive in the winter, you can prevent your fuel from gelling up.
  • Change your diesel fuel filters: Diesel fuel filters are the most common freeze point for diesel fuel. Because only a minimal amount of diesel remains in the filter while your vehicle sits in subzero temperatures overnight, it freezes much easier and much faster than it would in the tank. Swapping out your old filter for a new one can reduce your chances of gelling — you don’t know if your current filter is partially clogged, which makes gelling more likely.

There may be 50 different kinds of diesel engines, but all of them will benefit from the above winter weather maintenance. Even if you consider your vehicle to be nothing more than a way to get from Point A to Point B, prepping your engine for subzero temperatures is still a wise decision; if you don’t dedicate the time to your diesel fuel lift pump and battery, you might end up going nowhere fast.

Funky Fuel Pumps: Upgrading Your System With Performance Injectors

If you’re one of the people who treat their vehicle like their child, you understand the importance of quality. When it comes to efficiency, diesel is as high-quality as you can get: the diesel engine rates number one for most efficient internal combustion and can run you between 400 and 800 miles on a single tank.

While your diesel vehicle is already doing great, sometimes we feel the call of the wild — an urge to really ramp up the speed and power and feel that engine rumble. Upgrading your fuel system is one of the easiest ways to do just that.

Parts Of A Whole

Diesel fuel systems are comprised of several components: the tank, which of course holds the diesel fuel; the fuel air separation system, which does exactly what it says on the tin; the diesel fuel lift pump, which is responsible for pulling fuel from the tank to the injector; and then the injector, which injects the fuel into the engine’s internal combustion chamber. Diesel fuel pumps play a major role, but investing in performance fuel injectors first can maximize your vehicle’s fuel delivery and atomization.

Depending on your vehicle, you have a variety of different types of performance fuel injectors to choose from. However, we recommend you choose a provider that can ensure a custom fit; these injectors are created and designed for your make and model, ensuring and original equipment (OE) fit. While doing your research, look out for companies that rigorously test for leaks, precise pressure, and spray pattern consistency — it shows that they’re as dedicated to your satisfaction as you are.

Once you select an injector that works with your system, you may want to look into upgrading your diesel fuel pumps to get even more power. High-flow diesel fuel pumps ensure optimal fuel flow to increase horsepower, torque, and throttle response.

It can be quite astonishing how a few simple changes can turn a boring diesel car or truck into a powerful beast. The amount of power you want (and money you’re willing to spend) dictates what performance fuel injector and fuel pump system you end up with. So, what are you waiting for? Go show that road whose boss!

The Difference Of Diesel: A Look At The 5 Best Diesel Engines Ever Made

diesel fuel transfer pumpDiesel vehicles are favored among many blue collar workers. With enough strength to tackle the heaviest loads and enough power to get long-haul truckers where they need to go without breaking the bank on fuel, it’s no wonder that 10 diesel engine trucks are sold for every 100 trucks in America.

The secret comes down to the engine’s specific components: from diesel fuel lift pumps to diesel filtration systems, diesel engine manufacturers are bringing together pieces that will allow for a highly efficient machine. But even among the best, there are standout winners that tower above their brethren; whether they paved the way for greatness in diesel design or revolutionized the industry, here are the top five best diesel engines ever made.

  1. International 7.3L Power Stroke: The Power Stroke revolutionized diesel truck ownership in the United States. Offering reliability, these engines helped start a horsepower and torque race among the Big Three (Cummins, Power Stroke, and Duramax), and was instrumental in pushing diesel ownership into the mainstream.
  2. GM 6.6L Duramax: General Motors upped its game with the creation of the Isuzu-built Duramax in 2001. Now, the refined beast is capable of outrunning both Cummins and Power Stroke in the diesel power war.
  3. Caterpillar C12 Super Truck Racing Engine: This engine can propel a massive racing big ring to 100 mph in just 7.9 seconds. As a result, the Caterpillar team won several championships on the back of this indestructible monster.
  4. Wartsila-Sulzer RTA96-C: This powerful engine is used to move container ships, cruise liners, and generates a heck of a lot of force!
  5. International DT466: Fleet managers across the country love to power their medium-duty transportation trucks with the DT466 because they run forever, are efficient, supply good power for moving freight, and can be rebuilt right in the chassis.
  6. The Cummins B-Series: It may not have been the first, but the B-Series Cummins brought some much-earned respectability to diesel pickup trucks. With enough torque to relocate skyscrapers, the B-Series continues to shine.

From diesel fuel transfer pumps to fuel air separation systems, diesel engines truly do operate like well-oiled machines. As diesel has (as shown by the above 10 engines) and continues to prove, the fuel system is timeless — so don’t hesitate to upgrade yours with a new diesel fuel transfer pump today.

Piece By Piece: Fuel Pump Components Explained

electric diesel fuel lift pumpDiesel engines are estimated to have a 45 MPG highway mileage rating, making them the perfect choice for long- and heavy-haul trucking companies. Though there are a number of components that work together to achieve this stellar rating, one of the most important is the electric diesel fuel lift pumps — after all, you wouldn’t get very far if fuel didn’t make it to the engine.

However, diesel fuel systems are comprised of many pieces: the electric diesel fuel lift pump does not operate singularly, but rather in tandem with other (also very important) components. Let’s take a look at three of them.

  • Fuel Filter: Diesel fuel filters are responsible for removing any dirt, rust, or debris particles from the fuel before it enters the engine. Since even the tiniest piece of detritus can cause significant damage should it get into the powerful yet delicate structure of the diesel engine, it’s vital that your filter is not damaged itself. If your filter is old, it may become easily clogged: when this happens, you run the risk of fuel pump failure because the pump is forced to work much harder to force fuel through it.
  • Fuel Tank: Rust and dirt are an engine’s worst enemy. Though your fuel filter should stop these materials from getting into your engine, it’s not always a guarantee. If your fuel tank is badly rusted or contaminated with dirt, you may end up clogging your filter as larger granulations build up — then, you’ve got a repeat of the problem mentioned above. Physical damage to the tank itself, such as dents or distortions, can restrict fuel entry into the pump or fuel exist from the pressure regulator, which inherently affects efficiency and forces your engine to push harder.
  • Fuel Pressure Regulator: If the diesel fuel pressure regulator fails, fuel pump performance suffers. The pressure regulator will stick closed or the return line will become restricted, which will cause the fuel pump to operate at maximum fuel pressure. Again, you really don’t want your vehicle to be operating at such a high-pressure, extra force capacity because it can cause damage.

If any of these systems fail, engine efficiency suffers. As a result, it’s crucial to check the state of each during yearly inspections; When it comes to your diesel vehicle, it’s best not to skimp.

How To Troubleshoot Common Issues With Diesel Fuel Pumps

When your vehicle has an issue with fuel delivery, the rest of it will undoubtedly be compromised. Maintaining the integrity of your vehicle’s diesel fuel pump is essential to maintaining the integrity of your entire vehicle. With as many as 50 different types of diesel engines on the market, knowing the ins and outs of diesel fuel pumps is important. Know these common issues and never experience detrimental vehicle failure.


Dirty Fuel


The best diesel fuel pump injector is a clean diesel fuel pump injector. As residue builds up in the diesel fuel supply system, a surprising amount of grease, grime, and gunk clog up the entire pump. The area where the fuel leaves the injector and enters the combustion chamber, known as the spray tip, is especially prone to seeing the backed-up residue. This clogged tip is often the issue when an engine sputters or hesitates during acceleration. Be sure to use high-quality diesel fuel to prevent this build up as much as you possibly can.


Improper Injection Timing


Defective parts of the fuel injector pump can negatively affect the timing of the fuel transfer process. This typically happens when the injector pump’s O-rings or ball seats are defective themselves. While this is a fairly common glitch in diesel fuel pumps, it typically requires an entire rebuild or replacement to fix the defective parts.


Low Fuel Tank Level


Diesel fuel pumps need a good amount of fuel inside of them to run smoothly. The fuel serves as a lubricant for the fuel pump bearings. When you run your vehicle with a fuel tank that is as close to empty as possible, you’re not providing your pump with much lubrication and it will eventually destroy the pump. When a lack of fuel wears out the fuel pump bearings, the injectors do not receive the fuel at the pressurized level they should be.


Debris Inside Injector


Small visitors to the inside of injectors, like pieces of dust and debris, can clog the entire injector. A tiny object could also leave the injector open at all times. Injectors need to close for optimal operation, and when they can’t the cylinder performance is compromised.


Keep an eye out for issues like this with your fuel lift pumps. When you catch issues early, you can work toward a solution more quickly.

3 Factors To Consider When Choosing A Fuel Pump

If you have the vehicular knowledge necessary to pick and choose between individual parts, you’ll know the importance of the fuel lift pump. Often located within the fuel tank, different diesel fuel pumps provide different outcomes in terms of efficiency and power. There are a number of fuel pump manufacturers out there, so the journey to the perfect one may end up being more difficult than you expected. If you’re trying to find the right diesel fuel lift pump for your vehicle, consider the following three factors.


  • Horsepower: Your engine’s horsepower (hp) determines how much fuel flow is required to support it. As horsepower increases, so too does the volume of fuel needed to support that power. Focusing on the 10hp per gallon (or 2.64hp per liter) can help you estimate the volume to power ratio in your vehicle. However, you can only actually know your gallon per horsepower ratio if you take into account the fuel pressure required for your engine.


  • Fuel Pressure: Different engines require different fuel pressures. Fuel pressure has a large effect on how much flow a pump can produce, so it’s vital that you know what your engine’s maximum pressure is. Fuel pumps flow at their highest volume when there is no pressure (known as free flow), but as the pressure increases, the flow decreases. Every pump has a different flow volume at a given pressure, so taking a look at a flow chart of the pump you decide to buy can make the process a lot easier.


  • Voltage: Fuel pumps have different flow rates at different voltages. When the voltage increases, the speed of the pump will also increase, which then increases its flow at any given pressure. Most cars produce around 13.5 volts when running. However, if yours does not produce 13.5 volts, you can examine the flow ratings of a pump at 12 volts instead to be safe.


A single tank of gas can power a diesel engine between 400 and 800 miles; to get the most out of your tank, you must have a fuel pump that is optimized for your vehicle. If you’re able to take into account the three factors described above, you should have no problem sorting through all the fuel pump manufacturers and getting the most bang for your gasoline-buck.

Mechanical vs Electric Fuel Pumps: Which Is The Right Option For You?

Nobody ever said the mechanics of a car were easy to understand. Unless you were born with a ratchet in one hand and a wrench in the other, we’re guessing the complexity of diesel fuel lift pumps and diesel filtration systems go right over your head. And, if that’s the case, how are you ever going to know what type of diesel fuel lift pump — mechanical or electric — is best for you and your vehicle? Easy: we’re going to explain both of them to you!


The Minutiae of Mechanical Pumps

Mechanical diesel fuel pumps have been around for decades, though the switch to electric everything these days has seen them becoming less and less popular. The work mainly on older engines with carburetors: the pump siphons fuel from the gas tank and pushes it to the carburetor when the engine is cranking or running. Though they won’t quite stand up to boosted applications or engines running nitrous with higher horsepower ratings, they are a convenient and affordable choice for those who simply use their vehicles to get from point A to point B. They’re quiet, require minimal effort to install, and (since they aren’t electric, obviously) have no wiring to muck around with or worry about. If you want to push your engine or give it a little extra kick, however, electric fuel pumps are the way to go.


The Excitement of Electric Pumps

For vehicles that really purr, pushing the limits and efficiency of your engine, electric pumps are essential. They’re needed in situations where higher fuel pressures are required (like boosted applications, nitrous, and fuel injection — the latter begins at 30,000 PSI). Sometimes, mechanical pumps simply won’t fit in your car, forcing you to go electric instead; however, they offer a wide variety of flow rates and pressure outputs, making them incredibly versatile and able to work well in many vehicles. Most electric fuel pumps require a 12 volt circuit with a relay that gives you multiple shut-off options, but they must be properly placed in order to guarantee efficiency. Although they’re more expensive, they are generally more efficient and safer options.


Essentially, your choice of diesel fuel lift pump relies on your personal needs, from budget to boosts. If you have any questions, you can always contact your local mechanic for advice.

Get Your Pump On: 3 Different Types Of Fuel Pumps

If you’ve ever purchased a car, you know how many versions, styles, and colors are available for each manufacturer. Unsurprisingly, what’s under the hood is as versatile; while all the necessary components are, well, necessary to keep the vehicle running, they come in a wide variety of designs based on personal use and preference. From diesel fuel lift pumps to diesel filtration systems, you have the freedom to decide (within reason and space limitations) what goes in your car. This article will focus exclusively on fuel pumps.


  • Rotary Vane-Style Lift Pumps: Rotary vane pumps contain a paddle-wheel device within a larger circular housing. The wheel is offset within this housing, which creates a crescent-shaped cavity. The paddles slide in and out as the wheel spins, drawing fuel into the pump through the inlet; when the fuel reaches the narrow point of the crescent on the outlet side, it is compressed and pushed through the outlet. These fuel pumps are highly efficient, but they make a lot of noise.


  • Gerotor-Style Lift Pumps: Gerotor pumps are high-pressure, high-volume electric fuel pumps. By utilizing two gears (a spur gear and a ring gear) that work together to rotate the cavity, suction is created on the inlet and pressure is exerted on the outlet; this even balance is what makes Gerator pumps so efficient and able to build high pressures — and all without making any noise. However, they are susceptible to damage from contaminants and can experience cavitation because of the strength of the vacuum they produce.


  • Diaphragm-Style Fuel Pumps: Diaphragm pumps use a flexible membrane (usually a rubber composite) that moves up and down inside a chamber. The fuel only moves in one direction within that chamber. A lever on the pump fits into a lobe on the camshaft; as the cam spins, the lever is moved, pulling the diaphragm down and increasing the size of the pump chamber, which draws fuel into the pump. When the diaphragm pushes up (aided by a diaphragm spring), the fuel is forced from the chamber and into the feed line. Although they are more resistant to damage from contaminants and debris (like water, scale, rust, and dirt), their high vacuum makes diaphragm pumps vulnerable to vapor lock or cavitation. As a result, they’re usually recommended for carbureted applications where higher pressures aren’t needed.

Unless you are a qualified mechanic, we recommend consulting a professional before making any purchases or changes to your vehicle. Whether your car runs on a diesel fuel supply system or uses regular gasoline, you’ll be able to find a product that best suits your needs.

Upgrading Your Diesel Fuel System: A Simple Guide

Diesel engines are still very much around, and not just in the trucking industry. Those who wish to boost power without sacrificing efficiency (as diesel engines rate number one for the most efficient internal combustion) usually fit a diesel engine into their vehicles — and if they want a little extra oomph, they’ll upgrade the diesel fuel system.

The Basics

Before you go digging around in your engine (or pay someone to dig around in your engine), it’s important to know the components involved in diesel fuel systems. Your engine will contain a diesel filtration system, complete with diesel fuel filters to ensure that no dirt or debris gets into that very expensive engine, an injection system, which is responsible for injecting the fuel that will be turned into mechanical energy, but — most importantly — your engine will contain a diesel lift pump.

The fuel lift pump transfers fuel from your tank to the injection system. Virtually every diesel has a lift pump of some kind, yet many people prefer to purchase and install aftermarket pumps to boost their power past factory settings.

Feel The Power

Modifying the amount of fuel that gets injected, either through programming (if your truck is computer-equipped) or manually, is one of the easiest ways to push your engine and “see what she can do”, so to speak. Unfortunately, most factory diesel lift pumps cannot keep up with the change: when supply fuel pressure drops, the injection pressure into the engine will also drop, and so will horsepower. In fact, running pressure that’s too low can potentially harm the injection pump and cause it to fail, so any time you modify your engine for more power and performance, you’re going to want to install a new lift pump as well.

Now that you understand how your system works, you can begin looking for a suitable lift pump. Low-pressure fuel pumps are inexpensive (carrying a price tag of around $100), but they almost always fail in diesel setups. It’s a much better idea to do your research and find a quality diesel lift pump that has been proven to succeed.

High Roller: Unbelievable Diesel Built LBZ Suburban

Human ambition and imagination have long achieved the most amazing and unbelievable feats. While souped-up, massive car builds aren’t usually the first things that come to mind when discussing profound human achievements, they are nonetheless still on the list. We have no doubt that you’d only have one thing to say when St. Louis native John Eilermann pulls up in his decked-out behemoth, fittingly named “High Roller”: check out the build on that one.

Eilermann had a few basic needs that transformed his 1972 Chevrolet Suburban into the monster it is today:

  1. He wanted a vehicle that was large enough to fit five to six people
  2. It needed to be able to handle his 300-acre property, off-road style

Originally, Eilermann was dead-set on building a Jeep or a safari vehicle to meet these needs — that is until he saw their price tags. Legitimate safari vehicles can run up to $150,000, so the wheels were set in motion to produce the luxurious and powerful High Roller.

Powered by a 6.6-liter LBZ Duramax diesel engine, this car has got it all: limo style seating, moonroof, and no backglass to truly give it that safari-style feel. Known affectionately as a “Duraburb”, High Roller rides on 2007 GM 11.5 AAM rear end with a Yukon Grizzly locker, and a 1989 Ford king-pin Dana 60 front end with a Trac-loc limited slip. Matched perfectly with the wheels and tires, High Roller uses a six-inch Rough Country lift kit, Bilstein rear shocks with remote reservoirs, and a 4:56 gear ratio. Although massive, its 550 horsepower and 1,050 lb-ft of torque give it all the power it needs.

Diesel engines are as powerful as they are efficient: boasting an average if 45 MPG highway rating, Eilermann will be able to have his fun without breaking the bank on gas. If you find yourself in the mood to create something as exciting and unique as High Roller, finding the best fuel lift pumps, diesel fuel filters, and diesel filtration systems are a good way to get started. FASS fuel pumps are known to be reliable and clean, and there are undoubtedly a number of FASS fuel system dealers near your location. Take a page from Eilermann’s book: start with a simple idea and take it to the professionals — your FASS fuel system dealers — to perfect.
