The AirDog PureFlow Raptor RP-4G-100 lift pump is a direct-fit replacement for 1998.5–2002 Dodge 5.9L Cummins applications. It restores the lift-pump function to maintain consistent fuel delivery to the injection system and is intended as the proper RP-4G-100 service replacement for those model years. Install where the original pump specification matches to retain correct fuel supply behavior.
