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:

• 4 bearing design w/intermediate shaft to reduce pump noise and increase reliability
• Low flow return to reduce aeration in fuel tank
• Demand flow to where the pump only sends what the engine needs
• Dual fuel feed to both side of Gerotor pump to decrease cavitation

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.
