Original Airdog 4G lift pumps for Cummins, Duramax and Powerstroke diesels efficiently remove air and vapor from your diesel fuel, improving overall engine reliability and performance! The Original 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! And with AirDog’s Quick Connect & Disconnect Fittings, install time is greatly reduced. 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 the Powerstroke and Duramax 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 as well as tip erosion.
The AirDog eliminates the 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!
