The Pureflow AirDog II-5G A7SABF592 DF-165-5G Air/Fuel Separation System is the newest generation in fuel delivery systems for your 1999-2003 Ford 7.3L Powerstroke. The 5G is engineered to be the longest lasting, most efficient, and quietest lift pump system offered.
The AirDog II-5G features a 4-bearing motor with an intermediate shaft that reduces pump noise and improves reliability. The demand flow design allows the pump to only send the necessary amount of fuel to the engine. A dual feed design supplies fuel to both sides of the gerotor pump to decrease air bubbles and cavitation.
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.

I am very pleased with my purchase. I am pleased with my experience dealing with CNC. I did a full fuel system build along with this pump so the install took a while, but overall it went very smoothly. So far the airdog is performing flawlessly.
