Manufacturer of Fuel Air Separation Systems and High Performance Lift Pumps for Diesel Powered Pick-up Trucks!

PureFlow AirDog® manufactures and supplies AirDog® Fuel Air Separation Systems and Raptor® high performance lift pumps for diesel pick-up trucks.

AirDog® works by using the Fuel Preporator®. The system can improve diesel engine performance by separating the entrained air from the fuel, also improving fuel economy through improved injection timing, increased power and better fuel burn. The effectiveness has been proved over millions of miles.

An engine equipped with the Fuel Preporator® has consistently shown a timely injection and will perform at peak power output and efficiency regardless of the fuel filter condition. Learn more about how AirDog® can improve your engine performance!
