Diesel Fuel Filter from FASS

FASS has a patented process that removes air/vapor with one efficient method while our competitor uses two methods. The FASS process allows for more consistent fuel pressure to be maintained while providing the ability to use more of the diesel fuel filter capacity than our competitor. The mass volume return (MFR) of the FASS Separation System will continually filter the fuel as all of the fuel exiting has passed through the diesel fuel filter.

FASS performance diesel parts filter at the GPH rating of the fuel pump, thus giving your fuel injection system the cleanest gas possible. The more often the gas passes through the diesel fuel filter, the cleaner the fuel. Our diesel performance competitors low volume return only cleans and filters the petroleum as it is needed by the engine because it only returns enough petroleum to separate the air.
