Product Description:

The PureFlow AirDog A4SPBD005 150GPH Air/Fuel Seperation System for your 2005-2018 Dodge 5.9 & 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, everytime!
