The PureFlow AirDog II-4G A6SABC114 DF-200-4G Air/Fuel Separation System is designed for use on the 2011 to 2014 Chevrolet and GMC vehicles equipped with the 6.6L Duramax diesel engine. The  PureFlow AirDog II-4G is the next generation in lift pump fuel delivery. The compact AirDog II-4G fuel air separation system provides increased engine performance as a long-lasting, efficient quiet lift pump. The compact AirDog II-4G provides the most effective technology designed specifically designed for the effective removal of water, suspended particulates, vapor, and entrained air from diesel fuel.

The AirDog lift pump returns the fuel Air/Vapor back to the tank through a filler neck tee. This PureFlow AirDog II-4G A6SABC114 lift pump system is sold as a complete kit with all required parts for a straightforward installation. Our Duramax kits usually see the largest performance gains as these trucks do not come with a lift pump from the factory.
