This is the AirDog II-5G DF-220 fuel system for the 2008-2010 Ford 6.4L Powerstroke. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. This system uses a 5/8" draw straw to pull fuel from the tank. The pressure side connects to the factory supply line on the frame rail. This fuel pump completely bypasses the factory fuel pump. The AirDog Air/Vapor return is sent back to the tank through a return “Y” that splices the AirDog return into the factory engine return. This is a 220GPH (Gallon Per Hour) lift pump system for highly modified trucks.
