FASS Fuel Systems is worldwide recognized as the brand to beat. This company leads the way when it comes to fuel air separation systems for diesel vehicles. It all started in a garage of Brad Ekstam who got interested in fuel systems and began their production back in 2003. Brad launched revolutionary fuel systems that provided the cleanest fuel and thus quickly got high demand. This lead to FASS Fuel Systems’ move to Marthasville, MO, its current location where the company still continues to innovate.

The advanced fuel air separation system is fabricated from aircraft quality aluminum and designed using the FASS Silencing Technology, Performance Radius Cuts, and Mass Flow Return Technology. The system is composed of a diesel fuel lift pump and fuel filter that are effective at removing air and vapor as well as dirt and debris, which allows for the most effective cleaning of the burning fuel. As a result, you benefit from boosted diesel engine performance, enhanced fuel mileage, and prolonged life of the injection system.

FASS’ fuel filters and water separators are thoroughly developed and extensively tested by a 3rd part laboratory to ensure the ultimate efficiency. The fuel pumps of the company are made with versatile applications in mind. They provide the strength and durability you expect from FASS Fuel Systems. Plus, they are guaranteed to handle different fuel pressures, even in the most challenging high-performance conditions. To help you maintain your fuel system in peak operating condition, FASS also provides a range of accessories like fuel lines, fuel pumps, fuel pressure regulators, fuel tank suction tube kits, and more. So if you want to get every last bit of juice from your diesel engine and increase its lifespan, FASS Fuel Systems is your choice.
