FASS (Fuel Air Separation System) Products

Fass LogoAir/vapor in diesel fuel is a common problem with any diesel vehicle where the fuel tank is located at a lower point than the engine. The movement of the fuel inside the tank, and the process of fuel transfer under these conditions creates as much as 10% air/vapor within the fuel. Symptoms of air/vapor can be low horsepower, poor fuel mileage, excessive smoke, injector failure, hard starting, surging and rough running. You can eliminate this problem with a FASS Fuel Air Separation System and get "test cell" performance under real world conditions.

FASS Fuel Systems increase injection components life, improves fuel economy, lower EGT’s, lower emissions (both Carbon Monoxide and Carbon Dioxide), extends filter life, provides excellent cold weather starts and boost horsepower. We take pride in our filtration system and its ability at removing “ALL” types of fuel contaminants such as AIR, WATER, DIRT and VAPOR from diesel fuel providing your engine the cleanest fuel available.

With over 20 years of experience in building the “quietest” highest quality combination of Fuel Air Separation Systems (FASS) and electric diesel fuel pumps available worldwide. It is this experience and proven success that led FASS to use a Gerotor specific fuel pump that typically lasts at least 700,000+ miles and is backed by industry leading warranties.

The R&D department at FASS is continually improving the product line to exceed your performance and quality expectations. They use one of the highest grades of Aircraft Quality Billet 6061 T-6 Aluminum, as a major component along with motor specific brushes in their electric motors to maintain the same high quality standard and increase the overall life of their units. With over 90% of their machining, and all of the assembly and testing performed under one roof, they maintain the highest quality standards throughout the industry. Before shipping, each FASS system will undergo 20+ vigorous testing to insure they exceed your expectations.
