6 Tips to Keep Your Diesel Engine in Tip Top Shape

There are a number of reasons to go with a diesel engine for your truck. While only one in ten trucks sold in the United States has one, they have amazing gas mileage.  One tank of fuel can go between 400 and 800 miles. This is an mpg of 45 on the highway. If you have one, you probably want to keep it running well, you will be happy to hear that there are. From keeping your diesel lift pump to checking the air filters, there are things you can do for your engine.

  1. Keep an eye on the gaskets. Your diesel engine gaskets need some care and feeling in order for the engine to run properly. These are prone to damage from vibration. You should make it a point to keep the mounting bolts tight as ignoring this can be the cause of leaks. If you do have a gasket that is leaking, you should just replace all of them. When one is leaking, it means the others are about to start.
  2. Keep an eye on your air filters. It is important to check your air filters on a regular basis and change them as you need to. The good news is that if you are used to changing air filters in a gas engine, you should have no problem changing a diesel one. There are differences you should know about, however. Diesel air filters are most often found in the cold air collector. Another big difference between diesel air filters and the ones in a gas engine is that the entire engine needs to be shut down before you change out the filters. The powerful air intake system in a diesel engine can pull in just about anything around it. Shut it all down to be safe. Remember, it is a lot less expensive to replace an air filter than a diesel engine so do not skip this step.
  3. Keep an eye on your diesel fuel filters. In most heavy-duty engine setups there are two separate diesel fuel filters. Your primary filter can be found in between the engine itself and the fuel tank. Your second filter lives closer to the engine. This is responsible for cleaning the fuel before it is able to reach the fuel injectors and diesel lift pump. Again, the process to change out fuel filters in a diesel engine is similar to the one used in gas engines but it is always advisable to check your owner’s manual.
  4. Keep an eye on the fuel system. Diesel fuel systems need to be primed and bled from time to time. The fuel lines have to be properly bled of any air bubbles before you even think about changing the fuel filters. The fuel lines need to be clear. This can be done by using the manual primer pump. You can also check the diesel fuel pump. You will know when you have all of the air out of the system when the air-bleed screw stops hissing. Also, keep an eye on your diesel lift pumps at the same time.
  5. Keep an eye on the water separator. It is common for diesel engines to have a water separator. This is important for getting any water that has condensed out of the fuel itself. This happens all of the time. This lives oftentimes around the primary fuel filter. This can be drained manually by using the petcock valve. If you always keep the fuel tank at near full, you will prevent water from condensing in the first place.
  6. Get your truck ready for the colder months. If you live in a region with a real winter you will need to help it perform at its best. Cold weather can wreak havoc on a diesel engine. By adding an electric heater to your diesel engine, you can help it work better in very cold conditions. Adding starting fluid (only a tiny bit) to the combustion chamber can also help.

Owning a truck with a diesel engine can be a great value. When you pay attention to your diesel lift pump, filters, and other basic parts of the system you will keep it happy.

5 Components of Diesel Fuel Systems

One out of every 100 cars sold in America has a diesel engine. It’s estimated that cars with diesel engines can achieve up to 45 Miles Per Gallon (MPG) on the highway.

The elements of diesel fuel systems are designed to work together to inject a specific amount of pressurized and atomized fuel into the engine cylinders at the right time. When this fuel mixes with hot, compressed air, combustion takes place. This is unlike gas engines, where combustion is caused by an electrical spark. Because diesel fuel systems work differently than gas fuel systems do, they are designed with these differences in mind. Here are five components of a diesel fuel system, along with information about what they do.

1. The Fuel Tank.

A fuel tank must have the ability to store enough fuel to keep the engine operational for a reasonable amount of time. It must also be closed to avoid foreign particle contamination. The tank also requires vents to enable air to enter and replace fuel being used. Fuel tanks also need three additional openings; one for filling the tank, one for discharging fuel, and one for drainage.

2. The Fuel Lines.

There are three different kinds of fuel lines in diesel cars. Heavyweight fuel lines can withstand the high pressures between the fuel injection pump and the fuel injectors. Medium weight fuel lines are designed for medium to light fuel pressure existing between the fuel tank and the injection pump. Lightweight fuel lines can be used in areas subjected to little no pressure.

3. The Diesel Fuel Filters.

To prevent foreign particles from clogging the fuel system, the diesel fuel in most systems must be filtered several times. Conventional systems generally include three progressive filters; a filter screen near the diesel fuel transfer pump or the tank, then a primary fuel filter, followed by a secondary filter.

4. The Diesel Fuel Pumps

Diesel fuel transfer pumps are used in high-speed diesel fuel systems to automatically supply fuel to the injection system. Pumps often come with a lever for releasing air from the system and are nearly always jerk pumps.

5. The Fuel Injectors.

Fuel injectors are often considered to be the most significant component of diesel fuel systems. The even distribution of atomized, pressurized fuel throughout the cylinders leads to more power, better fuel economy, less noise from the engine, and a car that operates more smoothly.

Today’s diesel fuel injectors employ piezoelectricity. Wikipedia defines this as an electric charge accumulating in some solid materials as a response to applied mechanical stress. These types of fuel injectors are exceptionally precise and can withstand substantial pressure.

Cars having diesel engines can offer better fuel economy than some cars with gas engines. To perform at this level, diesel cars must have a fuel system with all of its components (fuel tank, fuel lines, fuel filters, fuel pumps, and fuel injectors) in proper working order. Understanding what these components do aids you in caring for them well.

Diesel Diligence: 3 Ways To Care For Your Fuel System

Diesel engines are notorious for their efficiency. In fact, a single tank of gas in a diesel engine is known to power a vehicle between 400 and 800 miles, explaining their popularity in the trucking industry. Despite these impressive numbers, they aren’t self-sufficient; like any quality product, diesel fuel systems need to be cared for in order to function at the highest level possible. If you’re car-savvy and know your way around diesel fuel lift pumps and diesel filtration systems, make sure that you’re keeping up-to-date on the following maintenance.

  • Fuel: Amazingly, repair statistics reveal contaminated fuel to be the cause of 90% of diesel engine problems. (This won’t be an issue if your filters are fully functioning, but we’ll get to that in a second.) If you’re unsure whether or not your fuel is dirty, simply pump some into a clean glass jar and wait a few minutes; if any contaminants settle to the bottom, you’ll know that it’s time to find a new source of diesel fuel.
  • Prevent algae: Just like mold on bread, algae and fungi can thrive in fuel tanks. These microbes depend on both fuel and water to survive, though eliminating water from your tank is major; unfortunately, that’s not always possible. To cover all your bases, your fuel should be treated with a biocide to ensure no bacteria can grow.
  • Tank: However, even the most meticulous of drivers can end up with dirty fuel and microbial growth. To stay on top of your fuel system’s health, it’s advisable to clean out the tank every so often; every few years (at the very least), draw some fuel from the bottom of the tank to check for water and/or sediment — it’ll be worth the effort in the long run.

When it comes to the air fuel separator diesel doesn’t always make things easy. Sometimes — no matter how well-versed you are with the intricacies under the hood — it’s hard to find your way around. By having a professional take a look every year (or more, depending on your vehicle’s age), you can guarantee that your diesel fuel pumps and filters are in perfect working condition. Only by caring for your diesel fuel systems will they continue to perform with quality and efficiency.

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!

  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.
