This is the AirDog I FP-100 fuel system for the 1994-1998 P-Pump 12V Cummins. This system mounts to the frame rail using the supplied sandwich plate mounting system. This system utilizes the factory suction port in the fuel module for suction and connects directly to the P-Pump, bypassing the factory fuel filter housing. 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 100GPH (Gallon Per Hour) fuel system. Check out our installation manual for a list of parts that are included with this kit.
