Aftermarket fuel systems are a must have on today's modern diesel engines! With modern diesel fuel systems running tighter tolerances, higher injection pressures and higher temperatures, the failure prone OEM fuel supply system barely has adequate fuel supply volume and filtration to keep up with the needs of the injection system. Add to a already bad fuel supply situation a horsepower increasing tuner or bigger injectors or both and it's a recipe for accelerated injection pump and injector failure! On top of that, unrealized performance and milage gains that are left on the table because the fuel injection system was starved of needed fuel supply! This is why we recommend the FASS fuel system to our customers! Diesel System Services has been selling and installing FASS fuel systems since 2003.
