Pureflow Airdog A7SABD525 Features:
This is the AirDog II-5G DF-165-5G fuel system for the 1998.5-2004 Dodge Ram VP-44 and early CP3 5.9L. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A Fuel Module Upgrade Kit is installed in the factory fuel basket to pull fuel through a factory-style 1/2" bulkhead fitting. This will bypass the factory in-tank lift pump. The pressure side connects directly into the side of the injection pump, bypassing the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through the factory 3/8” suction line once the module is modified. This is a 165GPH (Gallon Per Hour) lift pump system for moderately modified trucks. Check out our installation manual for a list of parts that are included with this kit.

Remove Air From Your Diesel Fuel System for Maximum Performance

The AirDog II-5G delivers unmatched protection and performance for your lift pump system. Its patented air separation, combined with a water separator and fuel filter, ensures that your expensive injection system components receive clean fuel. Designed to overcome power loss at higher altitudes caused by factory fuel pumps, the AirDog II-5G is the first diesel system to feature an integrated diaphragm fuel pressure regulator, offering enhanced adjustability, improved fuel flow under pressure, and boost compensation. With larger porting, it reduces cavitation and noise at the inlet of the high-flow 220 GPH pumps. Every AirDog II-5G system includes upgraded wiring harnesses and connectors for improved durability and reliability.
