Why did my VP44 Injection Pump Fail?

Common Failures:

  • Fuel Delivery (Lack of fuel pressure from the lift pump will starve the VP44 of the fuel it requires to be cooled and lubricated. This heat and lack of lubrication, most often, leads to either a pump failure internally or electronically.)
  • Fuel Contamination (Corrosion of your pump internals, caused by contaminated fuel or the use of alternative fuels, will cause drivability issues and lead to a failure of the pump.)
    • Always purchase fuel from trusted sources and run a high quality fuel additive, such as XDP’s Diesel Power Plus, to help avoid contamination issues.
  • Electrical Failure (Excessive heat and heat cycles over time will cause the electrical component on top of the VP44 to fail.)
    • There is little you can do to avoid the heat of the engine, but our best recommendation is to run a good aftermarket lift pump that provides the best flow of fuel to keep the pump cool.
  • Seized Rotor (Lack of lubrication from either running the pump out of fuel or the lower sulfur diesel fuel being used today.)
    • Running a high quality fuel additive, such as XDP’s Diesel Power Plus, increases fuel lubricity and helps extend injection pump and fuel system life.

Diesel Particulate Filter: Get to Know What’s Under Your Truck

All diesels from late-2007 are required to have an emissions device on them called a Diesel Particulate Filter. These filters dramatically reduce soot (particulate matter) emissions and have played a huge role in protecting diesel passenger vehicles from increasingly stringent emissions standards. Ford, GM and Dodge all equipped their trucks with these devices and in 2011 Ford and GM also equipped theirs with SCR (Selective Catalyst Reduction) as well as Dodge on their Cab and Chassis trucks, reducing emissions further and increasing horsepower by allowing the truck to be more aggressively fueled from the factory while still meeting emissions standards.

The DPF is similar in design to a catalytic converter and is placed after the catalytic converter in the vehicle’s exhaust. Its sole purpose is to block soot and reduce the emissions that make it out of the tailpipe. When the DPF filter becomes clogged, it needs to be heated to clean itself out. To accomplish this, the engine injects fuel in on the exhaust stroke so that it heats up and travels to the particulate filter, burning up any matter that is clogging the filter and allowing the truck to run correctly. The downside to this is that it takes a reasonably large quantity of fuel to clean out the DPF, or “Regenerate.”

The DPF works in conjunction with the EGR (exhaust gas recirculation) system which routes exhaust gas back into the engine to be burned again, which cleans up emissions by further breaking down the chemicals in the exhaust. The downside to the EGR setup is that it can reduce engine output because of the hot air being sent back into the engine and it dirties the inside of the engine over time. On the 6.0L Ford trucks, the EGR system was the cause of much more serious engine problems involving heightened cylinder pressures and blown head gaskets.

SCR, which is the injection of diesel exhaust fluid (DEF) into the exhaust to reduce NOx emissions, is another process that manufacturers are using to cut down on the emissions of these trucks as well as restoring lost horsepower. SCR allows the engine to fuel more aggressively while still meeting emissions standards because the urea in the DEF chemically alters the exhaust gas before it reaches the catalytic converter and the DPF, reducing the risk of damage to the DPF from over-fueling and cutting down on the frequency of the regen cycle. SCR’s biggest limitation is the requirement of fluid additions between oil changes; the fluid is not inexpensive and is not widely available yet.

That is a basic synopsis of how these devices function, but the most important thing to know is exactly how these affect your truck and the way it runs. For starters, a truck equipped with a DPF from the factory is likely going to return lower fuel economy than an older diesel that is not equipped with a particulate filter. The reason for this is simply that the regeneration process uses (potentially) gallons of fuel and that fuel is not being used to make horsepower or accomplish any work. Trucks that haul loads or are driven around town frequently will have to regen less often because the filter is more efficient under higher loads. Conversely, trucks that spend lengthy periods of time at idle or on the highway without a load will have to regen more frequently and in turn see reduce fuel economy.

Removing the particulate filter is a violation of Federal emissions regulations and is designed specifically for race and off-road use only. XDP carries all of the DPF, EGR, and catalytic converter delete setups for Dodge, Ford and GM as well as the required tuning for these vehicles.Trucks with a DPF equipped will benefit from the use of a quality fuel additive like XDP Diesel Power Plus (http://www.xtremediesel.com/xdpdieselpowerplusfueladditive.aspx). This additive boosts the cetane rating of the fuel by 5% and cleans out the fuel system so the engine produces lower emissions, which in turn means the DPF does not clog up as quickly or as frequently. These trucks are also more sensitive to maintenance, so making sure that the truck has fresh fluid and quality fuel in it will help improve the performance of the vehicle. Finally, doing a cold air intake, programmer and filter-back exhaust setup will help improve fuel economy and performance as well as lowering exhaust gas temperatures.

Particulate filter technology is evolving quickly and is going to be equipped on every diesel passenger vehicle designed and built in the foreseeable future. As the technology improves, horsepower and fuel economy will improve along with it. For now, the tips we outlined above will help you to improve the performance of your truck while abiding by federal emissions regulations, and for those looking for big horsepower race trucks, we have the delete pipes you need for those as well!

XDP’s Fuel Sump: A Way to Draw Fuel That Doesn’t Suck


For nearly a decade, XDP has been at the forefront of diesel performance. Diesel enthusiasts (you!) have known for years that the key to increasing horsepower is about increasing fuel and air to make the explosion that takes place inside of the combustion chamber larger, leading to more horsepower. One of the earliest modifications we recommend to do to any diesel truck is an upgraded fuel system like one of the offerings from Airdog or FASS. These fuel systems incorporate finer fuel filters than the factory units that trucks are equipped with along with water separators that ensure only the highest quality fuel makes it to your injection pump and then to your precious injectors. These units only create a slight increase in horsepower but improve the operating efficiency of the truck, the durability and reliability of the fueling system and they increase fuel flow and pressure to make sure that the truck is getting enough fuel for future horsepower upgrades.

Historically one of the challenges to installing these systems was the required installation of a high-flow suction tube, or draw straw. What happens sometimes if the suction tube is not installed close enough to the bottom of the tank is around a quarter tank the truck can start to suck air and lose fuel pressure, which results in a loss of horsepower and a troubleshooting headache. We have developed a solution to both simplify the installation of any aftermarket fuel system as well as improve the performance of them by ensuring they get a constant supply of fuel. Our fuel sump comes complete and ready to install with our internal horseshoe ring that allows a simple installation that does not require dropping the fuel tank.

The reason our fuel sump works so much better is simple: It uses the principle of gravity to its advantage. Fuel comes down into the sump rather than having to be drawn up, which means that the fueling is always ready and waiting for your aftermarket lift pump to send to your injection pump. We designed the sump to work with both a stock tank as well as an aftermarket high-capacity unit so you can get both range and effective fueling from your rig.

With XDP’s fuel sump you can accomplish two important goals: Improving the performance of your aftermarket lift pump and simplifying the installation of your new fuel system. At just $149.95 you can’t go wrong with a fuel sump for your truck, it’s the only sump good enough to wear the XDP logo!


Diesel Performance Basics

Diesel performance is not just for those looking to take their truck to the track for the best quarter mile time. Most of our customers are looking for more power for towing and hauling, or just to have it when they need it for everyday driving.

The big misconception is that performance products will kill your fuel mileage, void your warranty and cost big money. This couldn’t be less true!  In most cases you do not loose millage, but actually increase it: depending on your driving habits of course. Today’s performance modules leave no ghost so if you take the unit out and bring the vehicle back to the dealership, your warranty will not be void because they will never know it was there. Your exhaust, intake and gauges will most likely not void any warranties. There are performance options for every budget, so if your looking to spend a few hundred-or a few thousand-we have something for you at www.xtremediesel.com

The Key to getting more power out of your truck


Monitoring your diesel engines vitals is one of the most important things you can do.The more information you have the better you will know how to safely run your diesel with more power.

Air Intake Systems

The basics of making power are simple. It begins with airflow, high-flow conical air filters are the first step to increased airflow to the engine. Steel heat shields or molded plastic air boxes keep hot air out and fresh, cold air flowing to the filter. Velocity stacks and precision-designed intake tubes provide smooth, uninterrupted airflow to the turbo.

High-Flow Exhaust

More air in needs more air out. By installing a high-flow exhaust system you will see an increase in horsepower and torque. Fuel mileage gains may be noticed as well as a decrease in exhaust gas temperatures (EGTs). By lowering EGTs you will increase your turbo longevity.

Performance modules/programmers

Getting huge power and better fuel economy couldn’t be easier. Electronic performance products fall into 3 main categories, Modules, Tuners and Chips. All three types electronically modify factors such timing, injector pulse rates, fuel delivery and more. Selecting the right unit for you depends on your intended purpose for the vehicle.
