PureFlow’s Original AirDog 4G efficiently removes air and vapor from your fuel improving overall engine reliability and performance. The AirDog provides the proper pressure and flow of fuel to your engine under virtually all operating conditions for peak efficiency with consistent and maximum power output!
This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A 1/2" draw straw is used to pull fuel from the tank, bypassing the in-tank fuel pump. The pressure side connects directly to the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) lift pump system.
The compact AirDog provides the most effective technology designed specifically for pickups to remove water, particulates, vapor and entrained air from 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.
