AirDog II-4G DF-165 Air/Fuel Separation System — 1994–1998 Dodge 5.9L Cummins
The AirDog II-4G is the next generation in diesel fuel delivery, engineered specifically for your 1994–1998 Dodge 5.9L Cummins. By removing air, vapor, and contaminants from your fuel before it reaches the injection pump, it protects your expensive fuel system components and unlocks the full potential of your engine.
Why You Need a Lift Pump
Your stock Cummins relies on the injection pump to pull fuel from the tank — a design that leads to aeration, cavitation, and premature pump failure, especially under load or at high elevation. The AirDog solves all of that by delivering clean, air-free fuel at a consistent pressure.

- Removes air, vapor, and contaminants from fuel
