Made in the USA. A division of?Fltr Solutions Technologies, LLC(R), going to market as FST Performance(R), is a ROLLINS?Performance Manufacturing company.?FST's fuel filtration Syss represent a significant advancement in water-stripping technology and provides the highest in filtration efficiency. All of the FloMax(TM) Fltrs were designed-gasoline, ethanol and methanol based gasolines and?racing fuels. The TurboFyner(TM) diesel Syss were designed-petroleum diesel, vegetable oil and biodiesel Fltring. With all of the changes in today's fuel(s) and fuel injection, the one thing that is more important than ever before, and has been the one missing piece in the street-performance and racing markets, is a fuel Fltr?that really Fltrs the fuel?and?separates water,?yet with the flow needed-today's performance/racing engines.?Most of our?fuel Fltr competitors compromise filtration efficiency-flow.?Due to the large square inch capacity of media,?FST's?FloMax(TM)?maximum flow (300-350 GPH) and highly efficient 4 and 3 micron filtration and water separation make the?FST?line the most innovative and efficient Sys ever developed. Stainless steel screen fuel Fltrs (like most competitors) do nothing to shed/stop water and may only Fltr down to 10 micron. In fact, several fuel injector manufacturers and rebuilders use?FST? 3 micron fuel Fltrs on their equipment because of?FloMax?efficiency and flow rates.
