AirDog II-5G DF-165 Air/Fuel Separation System — 1994–1998 Dodge 5.9L Cummins
The AirDog II-5G is the latest and greatest in diesel fuel delivery for your 1994–1998 Dodge 5.9L Cummins. The 5th-generation design delivers cleaner, air-free fuel at consistent pressure — protecting your injection pump and injectors while maximizing engine performance.
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.
Features
- 165 GPH flow rate — ideal for stock and mildly modified engines
- 5th-generation design with improved efficiency and reliability over the 4G
- Removes air, vapor, and contaminants before they reach your injection pump
- Extends the life of your fuel system components
- Fits: 1994–1998 Dodge Ram 2500 / 3500 5.9L Cummins (P-Pump)
