fass decibels sound quiet
FASS Silencing Technology (FST) was developed by the engineering team at FASS Fuel Systems to help reduce the noise created by aftermarket fuel and air separation diesel lift pumps. By using radius cuts, tighter tolerances on all gears and a high quality military Spec’d Coating over the aluminum base, FASS Fuel Systems was able to develop the quietest fuel air separation system on the market.

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 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.
