This is the AirDog I FP-150 fuel system for the 2008-2010 Ford Powerstroke 6.4L. This fuel system replaces your factory low pressure frame rail mounted fuel pump. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A 1/2" draw straw is used to pull fuel from the tank. The pressure side connects directly to the factory injection pump feed line on the frame. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) lift pump system. Check out our installation manual for a list of parts that are included with this kit.
