Fuel Air Separation System 150/150 Standard - 25"
Air can cause vibrations and reduce the life of your fuel system. The fuel system can suffer excess wear because of the cavitations air creates in the pump and injectors. By removing the air from the fuel, the Fuel Air Separations System (FASS) enables the engine to run more smoothly and with more response. It also improves engine injection timing consistency. The FASS can result in fuel mileage improvement of up to 1/2 MPG and as much as 35 additional horsepower. FASS can also extend the life of the injectors and injection pump. A GT splitter valve is needed to route the return fuel to each tank.
Standard FASS = 150 gallons per hour.
