Fits 2001-2016 Chevy / GMC 2500HD / 3500HD
*2001-2004 LB7, upgraded CP3 and tuning may be required*
This is the AirDog II-5G DF-165-5G fuel system for the Duramax 6.6L Diesel. This diesel lift pump mounts to the frame for a clean looking installation. The suction side hooks up to the factory suction fitting in the fuel module. 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 lift pump system is one of our easiest installations. Our Duramax kits usually see the largest performance gains as these trucks do not come with a lift pump from the factory. This is a 165GPH (Gallon Per Hour) fuel system for moderately modified trucks.
Carryover features from AirDog II-4G:
DmaxStore Note: We utilize the OTC 6754 Duramax Fuel Pressure Gauge to check the fuel pressure from the lift pump at the test port towards the passenger side of the engine.
