Reliability and Performance! Two powerful reasons to add an AirDog^® II to your diesel pickup!

The AirDog^® II provides the proper pressure/flow of fuel to your diesel engine under virtually all operating conditions for PEAK EFFICIENCY with CONSISTENT and MAXIMUM POWER OUTPUT!

The compact AirDog® II provides the most effective technology designed specifically for diesel pickups to remove water, particulates, vapor and entrained air from diesel fuel. The AirDog® II 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 and also tip erosion.

The AirDog^® II 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^® II also provides the fuel pressures and flows your diesel engine needs to produce maximum power, any time, every time!

For serious performance seekers, whether you run a Cummins Turbo Diesel on the daily grind or for weekend pleasure, the AirDog® II has something to offer you!

*NOTE:  Unsure of whether you need the Airdog 100 or the Airdog 150 or even the 165 or 200?  Put it this way...if your truck is stock, or moderately stock (70hp chip or mild injectors) you want the 100.  If you've added a chip or two, larger injectors, or even a modified injection pump, you will want the 150.  If you're the latter and in need of an adjustable regulator to perfectly match your specific fueling requirements, then you want either the 165 or the 200 for heavily fueled trucks.

*NOTE:  Please choose model year of truck in drop-down box below.

*NOTE:  On 1998.5-2004.5 model year Cummins, these trucks could have the factory lift pump either on the side of the block or in the fuel tank.  If you have ever had the factory lift pump replaced, it is most likely now in the fuel tank (called the retrofit kit by Dodge).  It is very important that we know where your pump is to ensure we send you the proper AirDog pump.  If you turn your key to the "On" position (don't start the engine), listen for the "hum" from the pump and find its rough location (in the fuel tank or on the driver's side of the engine block).  Please make a note of its location in the Comments section at checkout, and also choose the appropriate listing in the drop down box.
