AirDog FP-150-4G A4SPBD103 Air/Fuel Separation System

The Pureflow AirDog FP-150-4G A4SPBD103 lift pump is a must-have upgrade for your 1994-1998 Cummins. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability.

The AirDog I FP-150-4G fuel system for the 1994-1998 Dodge RAM with the P-pump 12v Cummins is a diesel lift pump that mounts to the frame rail using the supplied sandwich-plate mounting system. A 1/2″ draw straw is used to pull diesel fuel from the tank. The pressure side connects directly to the P-pump, bypassing the factory fuel filter housing and fuel pump. Lines and fittings are included to connect the injection pump return, which would normally recirculate through the factory fuel filter housing, then to the injector return line, and is returned to the tank. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee. This is a 150 gph (gallon per hour) lift pump system.
