The Pureflow AirDog II-5G DF-165-5G 165 gph Air/Fuel Separation System A7SABC510 is the newest generation in fuel delivery systems for your 2011-2014 Chevy/GMC 6.6L LML Duramax. The 5G is engineered to be the longest-lasting, most efficient, and quietest lift pump system that AirDog has to offer.
The AirDog II-5G features a 4-bearing motor with an intermediate shaft that reduces pump noise and improves reliability. The demand-flow design allows the pump to only send the necessary amount of fuel to the engine. A dual-feed design supplies fuel to both sides of the gerotor pump to decrease air bubbles and cavitation.
The AirDog II-5G utilizes a diaphragm-style fuel pressure regulator, allowing the pump to be boost referenced and adjusted from 7-70 psi. The 5G system features larger 3/4-16 O-ring boss inlet and outlet ports. Also, 7/16-20 (-4) low-flow return is used to prevent aeration in the fuel being sent back to the tank.
AirDog’s Guarantee
The AirDog II-5G DF-165-5G for the 2011-2014 Chevy/GMC 6.6L LML Duramax is engineered with the most proven, quiet, and reliable motor technology on the market. It also retains the “demand flow” capabilities of the previous AirDog II systems. This means that there is a constant supply of clean, pure fuel available for your injector pump at all times. Any fuel not used by the engine is simply recycled back to the tank, so it will never “over-fuel” your system. The II-5G A7SABC510 uses the same better-than-OEM fuel filter (FF100-2) and water separator (WS100) as the previous AirDog II models. Pureflow AirDog products are manufactured in Shelbyville, Indiana, by a team of skilled workers with unsurpassed attention to detail and using the most stringent quality assurance.
