FASS Replacement Lift Pump for 1998.5-2002 5.9L Cummins (DRP02)

The FASS (DRP02) Direct Replacement Lift Pump is a complete replacement lift pump for your Dodge Cummins 24V 5.9L diesel engine and is designed to eliminate the common issues found in factory lift pumps that are known for their costly repairs. The DRP lift pump’s larger motor is strong enough to help supply your diesel truck with the consistent fuel pressure required by your VP44 to produce efficiency and horsepower. Simple to install, the DRP series pump can be installed by any novice mechanic and installed into factory mounting points making it the easiest installation of any aftermarket lift pump.

Factory Fuel Pump Failure

Failure of your factory lift pump is one of the most common component failures for the 5.9L 24 valve 2nd gen Dodge Cummins diesel engine. Both stock and modified engines suffer from this issue, with modified engines intensifying the weakness of the factory component, leading to premature failure. The main reason behind this pump’s inability to support the fuel demands of your Cummins engine is the fact that first, it’s a smaller weak motor that is located near the engine. This requires the motor to pull fuel from the fuel tank located at the rear of the truck against the momentum of your moving pickup. As with all diesel lift pumps, motors are designed to push fuel and when required to suck fuel over a long distance the added strain will overheat the motors, leading to a drop in fuel pressure. Low fuel pressures can cause a decrease in throttle response, fuel economy, and horsepower numbers and even cause damage to your VP44 injection pump.

DRP Relocation Brackets

To help the DRP series lift pump perform to its top potential FASS designed an optional pump relocation kit that will move the lift pump closer to the fuel tank, reducing the distance the lift pump needs to pull fuel from and instead placing fuel under pressure to push diesel to the engine. This is beneficial because all diesel lift pumps perform better as “Pusher” pumps and when under pressure the motor doesn’t need to work as hard to supply the fuel demanded by the injection system. This kit is sold separately (RK-02).
