FASS Diesel Fuel Systems
High Quality Craftsmanship
FASS Diesel Fuel Systems are engineered, manufactured, and assembled in the U.S.A., and we wouldn’t have it any other way. For our team, diesel performance isn’t just about accessories, it’s a way of life–as is the reliability of an American made product.
FASS Diesel Fuel Systems provide the cleanest fuel to the vehicles powering the infrastructure of our great nation. Whether it’s a Class 8 semi hauling Pittsburgh Steel, or a diesel pickup in cattle country, FASS is built to last.
Constructed from 6061 T6 Aircraft & Marine Quality Aluminum, and boasting such proprietary features as FASS Silencing Technology (FST), Performance Radius Cuts (PRC), and Mass Flow Return (MFR), FASS is truly a step above the rest, in both cutting edge technology and quality. Our diesel fuel pump and FASS fuel filters are manufactured with complete customer satisfaction in mind.
The high quality craftsmanship that comes from American made products are a point of pride for our dealers and partners.
