The Pureflow AirDog II-5G A7SABF595 This is the AirDog II-5G DF-220 fuel system for the 2008-2010 Ford 6.4L Powerstroke. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. This system uses a 5/8" draw straw to pull fuel from the tank. 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. This is a 220GPH (Gallon Per Hour) lift pump system for highly modified trucks. Check out our installation manual for a list of parts that are included with this kit.
The AirDog II-5G features a 4-bearing motor with an intermediate shaft that reduces pump noise and improves reliability. A dual feed design supplies fuel to both sides of the gerotor pump to decrease air bubbles and cavitation. The demand flow design allows the pump to only send the necessary amount of fuel to the engine.
The AirDog II-5G utilizes a diaphragm style fuel pressure regulator allowing the pump to be boost referenced and adjusted from 7-70 PSI The 5G system features larger 3/4-16 O-ring boss inlet and outlet ports. A 7/16-20 (-4) low-flow return is used to prevent aeration in the fuel being sent to back to the tank. CNC FABRICATION, LLC is a proud distributor of Pureflow Airdog Products.
