Airdog F165-4G Air/Fuel Separator Kit for 1998.5–2004 Dodge Ram 5.9L Cummins – Discontinued Model

Description

This is the AirDog II-4G DF-165 fuel system for the 1998.5-2004 Dodge Ram VP-44 and early CP3 5.9L. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A Fuel Module Upgrade Kit is installed in the factory fuel basket to pull fuel through a factory-style 1/2″ bulkhead fitting. This will bypass the factory in-tank lift pump. The pressure side connects directly into the side of the injection pump, bypassing the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through the factory 3/8” suction line once the module is modified. This is a 165GPH (Gallon Per Hour) lift pump system for moderately modified trucks.
