This is the AirDog II-4G DF-200 fuel system for the 1994-1998 P-Pump 12V Cummins. This system mounts to the frame rail using the supplied sandwich plate mounting system. A 1/2″ draw straw is used to pull fuel from the tank. The pressure side connects directly into the side of the P-Pump, bypassing the factory fuel filter housing. 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 200GPH (Gallon Per Hour) fuel system for highly modified trucks.
