FST Technology (FASS Silencing Technology)

To offer the quietest aftermarket diesel fuel pump and filtration system possible, our engineers here at FASS have designed ways to continuously decrease the audible sound of our FASS Titanium Series pumps without sacrificing our fuel pumps performance. As a rule for every 3 decibels of sound pressure decreased, the audible sound pressure of the pump is cut in half.

This is where our FASS Silencing Technology (FST), an exclusive feature only found on FASS Titanium Series fuel pumps, comes into play. Using various techniques in our FST process, we are able to proudly say that we do offer the quietest aftermarket pump and deliver superior performance.
