1998.5-2004 Dodge Cummins AirDog II DF-165 w/Built-In Adj Reg Quick Disconnect - A5SABD025

How is the AirDog II different than the Original Airdog? The AirDog II for the Dodge Cummins incorporates the demand flow. This means that it returns the smallest amount of fuel to the tank because most of it is recycled in the engine case itself. This small amount of fuel is taking the entrained air back to the tank rather than running to your engine. The AirDog II for the Cummins also has an adjustable fuel pressure regulator that you can set yourself for your application. Another feature is the high flow fuel module upgrade kit which eliminates the 1/4 tank issues associated with the Original AirDog application and most other fuel system setups. The return flushes back to the fuel basket or the fill neck to keep the fuel always supplied to the pump itself.
