Product Description

![VP44   Make sure to replace your lift pump every time you replace your injection pump for optimal fuel flow and injection pump life.   If you already have a new lift pump installed you can keep this one as a back up in case your pump fails on the road.   Buy piece of mind and save big with one of these VP44 pump packages.

Reman VP44027 Fuel Injection Pump

We are a certified 4 star remanufacturer. We use the most updated parts while building our pumps and replace all worn or damaged parts with brand new parts. We run every pump on a state-of-the-art calibration bench to insure that we ship each pump at or above original spec. Our calibration benches are updated quarterly with the most current calibration specifications, unlike some of our competitors. Don't be fooled by other companies claiming that they have an updated calibration that is unique to their pumps. We use the most current calibration available. We have over 20 years of experience and we stand by every pump that leaves our doors. We strive to ensure that our parts, quality, and service is 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 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.

Performance chip & add on disclaimer

Tampering with the VP44 pump's wires can cause premature pump failure.
If the wires are cut the pump is no longer warrantable, and any repairs that need to be made to the injection pump will be the buyer's responsibility. In the VP44 pump the fuel is used to cool and lubricate the pump, and the tolerances between the head and the rotor is very fine. Performance chip add-ons affect the cooling rate of the VP44 fuel injection pump. The pump will become hotter due to excessive RPMs from the chips programming. When the throttle is backed off the fuel to the pump is reduced, and the pump's cooling capabilities are greatly reduced. Since the VP44 pump is hotter from the increased RPMs the rotor seizes in the head and the pump fails. An alternative to cutting into the pump's wires is to use a chip that plugs directly into the trucks ECM. This approach will allow for an increase in HP while not excessively heating the fuel pump. A great example of this is the DiabloSport Power Puck, which is specifically designed to run the VP44 in safe RPM range.

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.

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.
