We’re proud to announce the XDP line of VP44 Injection Pumps for our 2nd Gen 5.9L 24V Cummins owners. While many VP44’s on the market are rebuilt with inferior quality components, XDP’s pumps have been remanufactured to most stringent specifications using only the highest quality genuine Bosch parts.
The stock replacement XDIPVR15X & XDIPVR17X is a perfect option for those needing to replace their failed VP44.
The XD191, known as the “H.O. XTREME” pump, is specifically designed to deliver the fuel needed to bring your truck to the next level. The H.O. XTREME pump is best suited with additional fueling and turbo upgrades. This pump ships with a pre-installed performance pump cover, eliminating the need to tap any pump wires.
XDP’s VP44 Injection Pumps are remanufactured using 100% Genuine Bosch parts. All remanufactured XDP VP44 Injection Pumps are warranted to be free from defects in materials and workmanship for a period of twelve (12) months from the date of purchase.
Why did my VP44 Injection Pump Fail?
- 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.)
- XDP recommends the use of an aftermarket fuel system that provides proper pressure and volume to keep your truck running properly.
- XDP also recommend the use of a fuel pressure gauge or BD-Power’s (BD1081130) Low Fuel Pressure Alarm Kit to help avoid fuel system damage.
- 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.
