The patented AirDog® II-4G (100) 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!
The AirDog® II-4G (100) system improves engine performance by:
Maintaining Correct Injection Timing
Eliminating Spray Pattern Disruption
Allowing for a Full Power Stroke and Complete Burn
Increased Fuel Economy
Increased Power Output
Increased Torque Output
Longer Injector Life
Improved Throttle Response
Reduced Exhaust Emissions
Optimized Engine Performance
AirDog® II-4G also overcomes loss of power for diesel engines operating at higher altitudes.
AirDog® is proud to announce that the AirDog II-4G® is thequietestfuel system in the diesel market!
Dual Feed Gearotor Pump
