This is the AirDog II-5G DF-100 fuel system for the 1994-1998 Dodge Ram P-Pump 12V Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. The suction side hooks up to the factory suction fitting in the fuel module. The pressure side connects directly into the side of the P-Pump bypassing the factory fuel filter housing, and factory fuel pump. The injection pump return is tied into the engine return to eliminate the need for the factory filter head. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee.  This is a 100GPH (Gallon Per Hour) lift pump system for stock fuel trucks.
