This is the AirDog I FP-150-4G fuel system for the 1992-2000 Chevy/GMC 6.5L Diesel. 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 supply side is hooked up to the factory fuel line feeding the injection pump. The 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.
