The patented AirDog® II-4G  (165) has been quality engineered to remove entrained air and water vapor from diesel fuel. The result is a compact, long lasting, efficient, and quiet fuel system made with superior quality. Advancing the AirDog® Tradition with the 4th Generation Fuel System! 

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!

• Maintaining Correct Injection Timing
