Airdog II-5G 165 GPH Air Fuel Separation Lift Pump System 05-24 5.9L / 6.7L Cummins

Beginning with the 2005 model years, Dodge opted to move the diesel lift pump from being mounted in the engine bay to inside of the fuel tank basket to help avoid the lift pump failures that had plagued them since 1998.5 model years. Overall, it was a positive move on their part as failures were reduced, but it was also quickly determined that especially for those looking to increase the horsepower of their trucks, even a little bit, this pump was completely inadequate. And to make matters worse, this new positioning of the pump inside of the fuel tank made upgrading that much more difficult. Fortunately, AirDog has a complete system that includes all of the components you'll need to make sure you'll never have to worry about fuel pressure again!

The AirDog II-5G is an all in one premium fuel pump and filtration system for your 2005-2018 Cummins diesel. This system removes water, particulates, and entrained air from the diesel fuel. The entrained air that is separated from the fuel is returned to the tank through a small return fitting. The fuel is delivered to the engine at the correct pressure and flow rate to meet the demands of the engine under all operating conditions.

The AirDogII-5G DF-165 systems feature a built in adjustible diaphragm pressure regulator. All AirDog II-5G systems include a complete installation kit. The AirDog II-5G, for this particular application, is preset at 17 psi from the factory for a stock application. The regulator is adjustible up to 55 PSI so you can fine tune the system to perfectly match up to your current and future performance upgrades.
