Item Specific:

This is the AirDog II-4G DF-165 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, high volume. If you are looking for a fuel pump that bypasses the factory pump, you will need part number A6SABF489. 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. This is a 165GPH (Gallon Per Hour) fuel system for slightly modified trucks. Check out our installation manual for a list of parts that are included with this kit.

AirDog II-4G Fuel Air Separation System with Fuel Demand Flow Technology and Enhanced Features AirDog II-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water. The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gerotor fuel pump. The fuel with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump. The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog II-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port. The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator. Quality Engineered to Remove entrained Air/Vapor, water, and particulates down to 2 micron from diesel fuel. 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!
