AIRDOG II-5G A7SABD524 DF-165-5g AIR/FUEL SEPARATION SYSTEM 1994-1998 Cummins

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)
