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.
