FASS Diesel Fuel Systems will return on Tuesday, September 8, 2026, for a holiday event.

We, at FASS Fuel Systems, have over 19 years experience in building the quietest, highest quality Fuel Air Separation Systems and electric diesel fuel pumps available worldwide. It is this experience that has lead us to use a Gerotor-specific fuel pump. Our success in the class-8 truck market has been above the rest. FASS pumps typically last 700,000+ miles, and our confidence is evident in our warranty. We offer warranties from 4 years on semi’s up to a lifetime warranty on pickup’s applications! With over 90% of our machining, and all of our assembly and testing performed under one roof, we maintain the highest quality standards in the industry. Each and every FASS system undergoes more than 20 vigorous tests before being shipped to ensure the performance exceeds your expectations. Our R & D department is continually improving the FASS product line to exceed your performance and quality expectations. We use one of the highest grades of Aircraft Quality Billet 6061 T-6 Aluminum, as a major component along with motor specific brushes in our electric motors to maintain the same high quality standard and increase the overall life of our units. Due to the brute size of our motor armatures we are able to achieve superior levels of stall torque. The increased amount of stall torque insures extreme cold weather starts by flowing gelling fuel.
