11-16 LML Duramax Airdog II 5G 165GPH Lift Pump

Any truck equipped with a Duramax engine produced between 2001 and 2016 did not come from the factory with a lift pump. This puts unnecessary stress on your injection pump and can lead to starving your engine of fuel. Help prolong your truck's fuel system with the addition of an Airdog lift pump!

Having run all of the 'major brands' of lift pump, I am very partial to AirDog. Viewing a side-by-side comparison, the AirDog is more efficient, better constructed, and has great warranty support, provided you submit your proof of purchase.

NOTE: BEFORE PURCHASE, DETERMINE IF YOUR TRUCK UTILIZES MINI OR MICRO FUSES IN THE UNDERHOOD FUSE BLOCK. IF YOUR TRUCK USES MINIFUSES, CHOOSE 11-14, IF YOUR TRUCK USES MICROFUSES, CHOOSE LATE 14-16. 

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. 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 system is one of our easiest installations. This is a 165GPH (Gallon Per Hour) lift pump system for modified trucks. 

Compatible with 2011-2016 LML and LGH Duramax engines.
