The PureFlow AirDog II-5G DF-220 fuel system is designed for 1994-1998 Dodge Ram P-Pump 12V Cummins, providing 220GPH (Gallon Per Hour) for heavily modified trucks. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A draw straw supplies fuel from the tank, and the pressure side connects directly to the P-Pump, bypassing the factory fuel filter housing and block-mounted pump. The injection pump return ties into the engine return, eliminating the need for the factory filter head. The AirDog Air/Vapor return is sent back to the tank via a filler neck return tee. Ideal for modified Dodge Cummins engines, this kit includes all components—see the installation manual for details.
