PureFlow’s Original AirDog 4G efficiently removes air and vapor from your diesel fuel improving overall engine reliability and performance. The AirDog provides the proper pressure and flow of fuel to your diesel engine under virtually all operating conditions for peak efficiency with consistent and maximum power output!
This is the AirDog I FP-150-4G fuel system for the 2015-2016 Duramax 6.6L. This system mounts to the frame jig in front of the fuel tank for a clean looking installation. A 1/2" draw straw is used to pull fuel from the tank. The supply side is hooked up to the factory fuel line feeding the CP4 injection pump. The return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) fuel system.
The compact AirDog provides the most effective technology designed specifically for diesel pickups to remove water, particulates, vapor and entrained air from diesel fuel. The AirDog replaces the Cummins factory lift pump and filter system, and enhances the fuel delivery to Powerstroke and Duramax engines with a commercial duty system.
