Fass Fuel System LogoWe choose FASS Fuel Systems at WORKING CLASS AUTO AND DIESEL

Our shop mechanics believe that our Pell City diesel truck drivers deserve the best and FASS Fuel Systems deliver just that.  FASS stands for Fuel Air Separation Systems and it replaces your factory diesel lift pump.  A lift pump is responsible for pulling your diesel fuel from the fuel tank and delivering it to the injection system up at the motor and the FASS System simply does this process better and more efficient than your factory lift pump.

To perform more efficiently than the factory lift pump, FASS first, utilizes a larger and more powerful motor; manufactured to push the fuel under pressure, rather than pull the fuel under a vacuum.  Second, the FASS System removes the contaminants from your diesel fuel by running it fuel through a dual filtration process that removes Air, Water, Dirt, and debris; giving you only the purest fuel possible.

With the help of a FASS Fuel System, you can improve your diesel trucks horsepower, torque, fuel mileage and extend the life of your diesel injectors.  FASS Fuel Systems offers fuel kits for Dodge Cummins, Ford Powerstroke, and GM Duramax pickup engines and universal Class 8 semi pumps for over the road truckers including Caterpillar, Cummins, and Detroit engines.
