The PureFlow AirDog II-5G DF-220-5G fuel system is designed for 2001-2010 Chevy/GMC Duramax 6.6L Diesel engines, delivering 220GPH (Gallon Per Hour) for moderately modified trucks. This diesel lift pump mounts to the frame rail with the supplied sandwich plate mounting system. The suction side connects to the factory suction fitting in the fuel module, and the pressure side feeds directly into the factory injection pump feed line on the frame. The AirDog Air/Vapor return is sent back to the tank via a filler neck tee, making this one of the easiest Duramax fuel systems to install. Ideal for Chevy Duramax trucks without a factory lift pump, this kit offers significant performance gains. Refer to the installation manual for a complete list of included components.
