The PureFlow AirDog A4SPBD009 150GPH Air/Fuel Separation System for your 2019-2020 Ram 6.7L Cummins provides the most effective technology designed specifically to remove water, particulates, vapor and entrained air from the diesel fuel in your truck. The AirDog is a lift pump and filtration system, that enhances the fuel delivery to your engine with a commercial duty system.

Your high performance diesel engine demands higher fuel flows. Yet higher fuel flows increase the vacuum at the fuel pump and agitation in the fuel tank. These factors generate additional air/vapor in the fuel system preventing your engine from producing maximum power and efficiency. Additionally, air/vapor can cause galling and pitting of the injector barrel/plunger assembly and also tip erosion. The AirDog eliminates air in the fuel that robs your engine of consistently greater performance and can also cause permanent damage to your injectors. The AirDog also provides the fuel pressures and flows your diesel engine needs to produce maximum power, any time, every time!

The Airdog works by pulling fuel from the fuel tank containing entrained air/vapor, particulate contaminants and unknown quantities of moisture. The fuel passes through the water separator which removes the water and large particulate contaminants. Then, the fuel with only entrained air/vapor and tiny particulate contaminants remaining, enters the fuel pump. Under positive pressure flow, the fuel passes through the fuel filter and the remaining particulate contaminants are caught and contained, the entrained air/vapor is also separated and returned to the tank. The clean fuel is now free of contaminants and water and flows at the proper pressures up to your engine. Each kit includes plumbing, hardware, wiring harness, mounting bracket and all components needed for installation.
