It was in 2003 when Brad Ekstam started producing Fuel Air Separation Systems (FASS) right in his garage. After gaining knowledge and experience in the industry since the 90s, Brad applied his skills to develop innovation in fuel systems. Demand for his products increased, which enabled him to acquire a bigger workshop in Marthasville, MO. Presently, this location is where all the FASS magic happens.

Brad never settled for just a "good" system. They aimed to exceed client expectations, which is why he brought in Spencer, his son, to the business to expand in R&D and customer care in 2013. A year after, FASS grew its name and customer base, making the company one of the highly regarded brands in the fuel systems market.

FASS offers complete satisfaction to its customers, upholding character and integrity in their products and name. The improvements made on the products over the years results in prolonged injection component lifespan, lower carbon dioxide, and carbon monoxide emissions, more economical EGTs, better fuel economy, longer filter life, higher horsepower, and efficient cold-weather starts.

Fuel contaminants such as dirt, water, air, and vapor are effectively removed through the filtration system, which feeds the engine with clean fuel. In their 20 years of existence, FASS has become the authority in fuel systems across the globe.
