We buy our pumps from an OEM certified remanufacturer. They use the most updated quality parts to build our pumps and replace all worn or damaged parts with brand new OEM parts. They run every pump on a state-of-the-art calibration bench to insure that we ship each pump at or above original spec. Unlike some of our competitors, their calibration benches are updated quarterly with the most current calibration specs available. Our manufacturer has over 20 years of experience and stands by every pump that leaves their doors. We strive to ensure that our parts, quality, and service are second to none.

NOTE:   When replacing the VP44 Injection pump on a 5.9L 24 valve Dodge truck it is very highly recommended that you also replace the feed pump ( AP4943048 ) and the fuel filter. These are the two major causes for VP44 pump failure. Failure to replace feed pump along with the Injection Pump may result in non-warranted damage. It is highly recommended that the feed pump be changed along with the VP44 injection pump. Also an early warning sensor can help prevent pump failure. ( 1081130 )

Performance chip add-ons & Tampering/Cut wires disclaimer:   Performance chip add-ons affect the cooling rate of the VP44 fuel injection pump. The use of Performance chip and add-ons will void the warranty for the VP44.Tampering with the VP44 pump wires can cause premature pump failure. If the wires are cut the pump is no longer warrantable.  Any repairs that need to be made to the injection pump will be the buyer's responsibility.

Defective VP44 Engine Codes:  The retrieval of codes does not constitute an engine diagnosis. However, there are some codes that usually indicate a defective VP44 injection pump. A current P1688 always means that the pump is bad, there is no further diagnosis required. Code P0216 is probably the most common code for VP44 Pumps. If transfer pump pressure has been checked and is O.K., the injection pump is defective. Other codes that are less common are P0180, P0181, P0215, P0251, P0252, P0253, P0254, P0370, P1287, P1689 and P1690. These codes USUALLY, but not always indicate a defective pump. There are wiring and power checks to be performed if these codes are present. These codes relate to Dodge pickups only, and are not for any other ISB application.

Common Problems with Newly Installed VP44 Pumps:   Some customers have reported running issues within the first month of VP44 pump installation. The usual symptoms are excessive blue or white smoke, or a 216 engine code. While these issues would point to a defective pump the usual cause is an incorrectly installed or damaged pump drive key.

The key is the small slightly offset half-moon shaped steel piece that is used to set the timing for the injection pump. It is installed in the slot on the pump drive shaft and is indexed to the slot on the drive gear on the engine.

To resolve this issue the pump should be pulled off and a new key installed. A new key will need to be purchased to replace the damaged one. There are several different key numbers and the correct one needs to be installed. Non-warrantable damage to the pump or engine may occur if an incorrect key is installed on a VP pump. To order a new key retrieve the key number and call us so we can ship the correct one. The key number can be found stamped on the key as well as on the pump name plate. The type of number to look for on the key or nameplate is a 3 digit number that starts with a zero, like .045, or .036.

While a damaged key is the most common cause of issues on new VP44 pump installations, there may be other factors as well (such as air leaks or a faulty lift pump). If you have any questions or need help troubleshooting a fuel system problem please feel free to call and speak with one of our qualified technicians.

Find the Engine Serial # on Cummins ISB 24 Valve 5.9L Engines:  The Engine Serial number is on the engine data plate, which can be found on the drivers side of the timing gear case (see below picture). The plate shows the CPL (control parts list) number, date of manufacture, timing specs, & the engine serial number. To insure that you receive the correct pump please type the Serial Number of your engine in the comments while placing your order. Before we process the order we will cross-reference your engine serial number to the correct VP44 fuel injection pump.
