Regardless of the type of fuel injection system your engine has, it will never perform at the designed efficiency with air and vapor entrained in the fuel. Air and vapor present in fuel contribute to increased fuel consumption and exhaust emissions, a loss of power, rough idle, and shortened injector life. The Champ™ High-Pressure Fuel Air Separator removes air and vapor from fuel and helps the engine perform as intended. Benefits include improvements in fuel economy, increased power output, smoother idle, and longer injector life.

These high-pressure systems do not have an integrated fuel pump but rather use the engine’s transfer pump for fuel flow, removing air and vapor from the fuel supply, filtering to 6-microns. The system mounts easily on the vehicle frame and is installed in the pressure supply line between the engine transfer pump and the engine. The separated air and vapor are returned to the fuel tank via a tee in the engine’s fuel return line. AirDog® Champ™ systems are currently available for most on-highway and off-highway diesel engines that include engine transfer pumps with which the Champ™ system can be plumbed in-line.

AirDog® Champ™ High-Pressure Fuel Air Separator can be installed onto many engines types, such as:

Cummins N14
Cummins ISX15
Cummins X15
Detroit Series 60 12.7l (1987-2002)
Detroit Series 60 14L (2003-2009)
Detroit DD15
Paccar MX-13
