This is the AirDog I FP-150 fuel system for the 1994-1998 Dodge Ram with the P-Pump 12V Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A 1/2" draw straw is used to pull diesel fuel from the tank. The pressure side connects directly to the P-Pump, bypassing the factory fuel filter housing and fuel pump. Lines and fittings are included to connect the injection pump return, which would normally recirculate through the factory fuel filter housing, to the injector return line and is returned to the tank. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) lift pump system. Check out our installation manual for a list of parts that are included with this kit.
