A6SABD425 Overview

This is the AirDog II-4G DF-165 fuel system for the 1998.5-2004 VP-44 and early CP3 5.9L. This system 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) fuel system for moderately modified trucks. Check out our installation manual for a list of parts that are included with this kit.

Airdog II-4G Overview

The advanced 4G technology offers protection and performance like never before! Our patented air separation, along with a water separator and fuel filter makes sure your expensive injection system components get all the clean fuel they need.

The AirDog® II-4G also overcomes loss of power due to driving in higher altitudes. The AirDog® II-4G System Improves Engine Performance by eliminating spray pattern disruption due to air entering the system. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases overall engine efficiency across the power and torque range!
