About FASS Fuel Systems

FASS Fuel System (Fuel Air Separation System) is a combination diesel FASS fuel pump and fuel filtration system that is designed to improve your diesel trucks fuel mileage, engine performance and extend the life of your diesel injection system.

FASS fuel system manufactures from American made components that are then assembled and tested in house using the highest quality components. FASS Diesel systems fit most Ford Powerstroke, Dodge Cummins, and GM Duramax Engines.

With a FASS Fuel Pump or FASS fuel filters only the purest quality fuel is delivered to your diesel engine by removing dirt, water and air through a two step filtration process while switching the fuel delivery process from a suction delivery to a pressure delivery, eliminating the possibility of reintroducing air back into the fuel after it has already been removed. FASS Fuel Filters (diesel) have a rating as low as 3 Micron, which provides superior protection from debris in your diesel fuel and engine. If you're in the market for a Fass Duramax Fuel Filter Delete Kit, look no further!
