Product Description
Overview: The AirDog® II-5G DF-220-5G is the high-flow (220 GPH) lift pump and air/fuel separation system built for hard-running 1994–1998 Dodge Ram 2500/3500 trucks with the 5.9L 12-valve Cummins (P7100). It delivers consistent fuel supply, removes entrained air/vapor, and stabilizes pressure at the P-pump for stronger, cleaner combustion and better reliability under heavy fueling, bigger injectors, and advanced timing.

FAQ
Will the DF-220-5G support big injectors and high RPM on a built 12-valve?
Yes—this 220 GPH system is sized for heavily modified 12-valves. It maintains stable supply pressure to the P-pump under sustained load, helping protect injectors and improve fueling consistency.
Do I need to keep the factory mechanical lift pump or filter head?
No—the pressure side of the II-5G ties directly into the P-pump and bypasses the factory filter head and block-mounted lift pump per the official instructions.
Is tank-drop required?
The kit uses a draw-straw installed in the tank for reliable supply. Follow the manual steps; most installs are completed with basic hand tools and careful routing.
What’s normal base pressure at the P-pump with this kit?
AirDog presets are targeted for the application; verify final pressure at the P-pump with a gauge after installation and adjust according to your tuning and component setup.
