Product Description
Upgrade your 1989–1993 Cummins 5.9L 12V with the AirDog II-5G DF-100 (100 GPH) air/fuel separation system. This frame-mounted lift pump removes entrained air/vapor and water, stabilizes fuel pressure to the VE-44 injection pump, and improves throttle response, idle quality, and injector life — without hacking the factory fuel filter housing.
