Enhance your 1999-2003 Ford 7.3L Powerstroke with the PureFlow AirDog II-5G DF-165-5G fuel system, a 165GPH (Gallon Per Hour) lift pump for moderately modified trucks. This system replaces the factory frame rail fuel pump and mounts to the frame rail using the supplied sandwich plate mounting system. The suction side connects to the factory suction line on the frame rail, and the pressure side feeds into the factory injection pump feed line. The AirDog Air/Vapor return is sent back to the tank through a filler neck return tee. Ideal for improving fuel delivery in modified Ford 7.3L Powerstroke engines, this kit includes all necessary components—refer to the installation manual for details.
