Pureflow Airdog A7SABC513 Features:
This is the AirDog II-5G DF-165-5G fuel system for the 2015-2016 Chevy/GMC 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. 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. 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) lift pump system for moderately modified trucks. Check out our installation manual for a list of parts that are included with this kit.

Remove Air From Your Diesel Fuel System for Maximum Performance

The AirDog II-5G delivers unmatched protection and performance for your lift pump system. Its patented air separation, combined with a water separator and fuel filter, ensures that your expensive injection system components receive clean fuel. Designed to overcome power loss at higher altitudes caused by factory fuel pumps, the AirDog II-5G is the first diesel system to feature an integrated diaphragm fuel pressure regulator, offering enhanced adjustability, improved fuel flow under pressure, and boost compensation. With larger porting, it reduces cavitation and noise at the inlet of the high-flow 220 GPH pumps. Every AirDog II-5G system includes upgraded wiring harnesses and connectors for improved durability and reliability.
