FASS Fuel Systems & Lift Pumps

About FASS

FASS stands for Fuel Air Separation System. The company got its start in 2003 and is based in Marthasville, Missouri. A FASS system pulls air and vapor out of the fuel and sends it back to the tank, and it filters water and dirt out before the fuel reaches the injection system. Cleaner, air-free fuel is easier on injectors and the high-pressure pump.
