This is the AirDog I FP-150 fuel system for the 2005 and up Common Rail Cummins. This system 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 CP3 injection pump, bypassing the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) fuel system. Check out our installation manual for a list of parts that are included with this kit.
