Upgrade your 2011-2016 Ford 6.7L 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 via a return “Y” that ties into the factory engine return. Improve fuel flow in your Ford 6.7L Powerstroke with this kit—check the installation manual for a full list of included components.
