This is the AirDog II-5G DF-165 fuel system for the 2015-2016 Duramax 6.6L Diesel. This diesel lift pump mounts to the frame jig in front of the fuel tank for a clean looking installation. The suction side hooks up to the factory suction fitting in the fuel module.
Our Billet Aluminum Bottom Sump with Integrated Fuel Return System completely eliminates the need to run the return of your aftermarket fuel pump to the top of the tank or cut into the fuel filler neck, therefore cutting install time tremendously!
This kit allows you to switch from the CP4 injection pump that come from the factory on the 2011-2016 LML Duramax trucks, to an earlier model higher volume CP3 injection pump. Failure of the CP4 pump almost always results in damaged injectors and a very costly repair bill. Converting to a CP3 injection pump will not only add to your reliability, but you will also have more flow potential.
