PureFlow AirDog 89-93 Dodge 12V 5.9L Cummins FP-150-4G Fuel Air Separation System

AirDog I FP-4G 150 GPH lift pump

AirDog makes this AirDog I FP-4G 150 GPH lift pump kit to fit 1989-1993 Dodge Cummins trucks. The AirDog FP-4G separates air and vapor from the fuel and routes it back to the tank, so the injection pump sees solid, bubble-free fuel.

It bolts to the frame rail with the supplied sandwich-plate mount. Fuel comes out of the tank through a 1/2 in. draw straw. Pressurized fuel goes to the injection pump, skipping the factory filter housing. Air and vapor pulled out of the fuel return by way of a tee fitted in the filler neck.

Who it's for

Diesel owners who want steady fuel pressure and cleaner fuel for the 1989-1993 Dodge Cummins.
