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 Demand Flow feeds the PowerStroke factory high pressure pump on 2009-2009 6.4L PowerStrokes. 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 GM Duramax on the daily grind or for weekend pleasure, the AirDog® II has something to offer you!

Unsure of whether you need the Airdog 100 or the 165?

Put it this way...if your truck is stock, or moderately stock (70hp chip) you want the 100. If you've added a 100hp programmer or larger, or even a set of injectors, and in need of an adjustable regulator to perfectly match your specific fueling requirements, then you want the 165.

These AirDog II systems are to be used with the stock high pressure lift pump
