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.

Your AirDog Comes with a Complete Installation Kit and Detailed Instructions.

• Relay Control Wiring Harness
• Frame Brackets
• AirDog Bracket & Spacer
• Return Manifold & clamps
• 1/2" ID Fuel Line
• All Required Fuel Fittings
• Mounting Hardware
• 1/2 Draw Straw & Bulk Head Fitting (AirDog 150’s)

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!

To understand how much of a difference the AirDog can make, below we have two pictures to illustrate an injector nozzle spray pattern without an AirDog and with an AirDog. First, the BEFORE spray pattern picture on the left shows graphically the effect of air and vapor in delaying the pressure buildup. Then, the AFTER picture on the right, with processed fuel from the Fuel Preporator®, demonstrates the spray pattern you can expect after installing your AirDog.
