FASS History

Brad Ekstam’s motivation to develop an industry leader in fuel/air separation systems for diesel engines has become a reality. Brad’s interest started in the early ninety’s and during that decade, he enhanced his skills and knowledge. Then as many ambitious entrepreneurs with a desire to succeed do, Brad started production of FASS fuel systems in his garage – the year was 2003. Demand increased, more space was needed, and FASS moved from Brad’s garage to its present location in Marthasville, MO. Accepting a good system has never been a goal of FASS – exceeding customers’ expectations is. Innovation continues as we eagerly head into the future, so look for new and enhanced products from Brad and his team.
