Get The Most Out Of Your Diesel Engine

Brad Ekstam, the driving force behind FASS Fuel Systems, developed a passion for fuel/air separation systems for diesel engines in the early 90's. By 2003, Brad was producing FASS fuel systems from his garage. As demand for his product grew, so did the need for more space, leading to FASS's relocation to its current facility in Marthasville, MO.

For Brad and FASS, "good enough" has never been the goal. They are committed to exceeding customer expectations at every turn. With a constant focus on innovation, FASS continues to push boundaries, with Brad and his team always looking ahead to bring new and improved products to the market. Their mission remains clear: to lead the industry and deliver cutting-edge solutions for diesel engine fuel systems.

FASS (Fuel Air Separation System) is a combination diesel fuel lift pump and fuel filtration system designed to improve fuel mileage, enhance engine performance, and extend the life of diesel injection systems. FASS's diesel fuel pumps and filters are proudly made in America, ensuring complete customer satisfaction.
