Airdog II-5G Fuel Air Separation System (165 GPH) - Ford 7.3L Powerstroke 1999-2003

This is the AirDog II-5G DF-165 fuel system for the 1999-2003 Ford Powerstroke 7.3L. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A draw straw is installed in the fuel tank to supply fuel to the pump.  The pressure side connects directly into the side of the P-Pump, bypassing the factory fuel filter housing and block mounted 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 the filler neck return tee.  This is a 165GPH (Gallon Per Hour) lift pump system for moderately modified trucks. Check out our installation manual for a list of parts that are included with this kit.
