The 1998.5-2002 Cummins got a pretty bad rap over the years for failed VP44 injection pumps, many claiming it was one of the worst decisions ever made to mate this supposed failure-prone pump on a Cummins powered Ram. Now, was it the VP44's fault, or was the engine bay mounted lift pump really the culprit? In most cases, the failure of the low output lift pump causes the demise of the injection pump. And to make matters worse, they continued to use a similar lift pump placement all the way through the 2004.5 model years before going to a higher output in-tank lift pump. So how do you fix one of these trucks for good? Easy, ditch the block mounted/fuel filter mounted stock lift pump and upgrade to an AirDog!

The AirDog II-5G is an all in one premium fuel pump and filtration system for your 1998.5-2004.5 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-220 systems feature a built in adjustable 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 adjustable up to 55 PSI so you can fine tune the system to perfectly match up to your current and future performance upgrades.
