FASS Fuel Pressure Regulators


FASS Fuel Systems adjustable fuel pressure regulators are intended for aftermarket performance applications requiring higher fuel pressures than a typical daily driver. These applications can vary from drag race vehicles, competition pulling trucks, or even high performance marine applications. FASS regulators have pre-drilled and tapped fuel pressure gauge ports that will make adjusting your regulator very simple. This eliminates any guesswork. In addition, FASS added a performance benefit by engineering a boost compensation port. This will allow you to run a line from your manifold to increase fuel pressure—very beneficial when under active acceleration and fuel demand has been increased.
