This is the AirDog I FP-100 fuel system for the 1989-1993 VE44 Cummins. This system mounts to the frame rail using the supplied sandwich plate mounting system. Fuel is picked up through the factory suction line, in the fuel module, to feed the AirDog. The pressure side connects directly to the VE injection pump, bypassing the factory fuel filter housing. 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.
