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!
This is the AirDog II-4G DF-165 fuel system for the 1999-2003 7.3L Powerstroke. This replaces the factory frame rail fuel pump. This system mounts to the frame rail using the supplied sandwich plate mounting system. The suction side hooks up to the factory suction line on the frame rail. The pressure side connects to the factory feed line to the injection pump. The AirDog Air/Vapor return is sent back to the tank through a filler neck return tee. 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.

This is the AirDog II-4G fuel system for the 2008-2010 6.4L Powerstroke. This system mounts to the frame rail using the supplied sandwich plate mounting system. The suction side hooks up to the factory suction line on the frame rail. The pressure side connects to the factory supply line on the frame rail. This fuel pump completely bypasses the factory fuel pump. The AirDog Air/Vapor return is sent back to the tank through a return “Y” that splices the AirDog return into the factory engine return. Check out our installation manual for a list of parts that are included with this kit.

This is the AirDog II-4G fuel system for the 2011-2016 6.7L Powerstroke. This system does not replace the factory frame rail fuel pump! This system supplies fuel to the factory fuel pump at a low pressure. It is added to the existing fuel system for the air separation and extra filtration only. This system mounts to the frame rail using the supplied sandwich plate mounting system. The suction side hooks up to the factory suction line on the frame rail. The pressure side connects to the fuel pump inlet. The AirDog Air/Vapor return is sent back to the tank through a filler neck return tee.
