FASS Fuel Sump Kits are the first sump kits available with no fuel line on the exterior of the tank. They come with a bulkhead fitting and a suction tube kit to pull fuel from the inside of the tank. These products are specially designed to help avoiding the lower bowl to prevent against the fuel getting mixed around thanks to the method by which fuel is returned to the tank - it shoots the fuel at an angle.

Starting from the vision of founder Brad Ekstram to develop a capable fuel/air separator system for diesel engines, Fass Fuel has grown into a company synonymous with quality and excellence. Ekstram honed his skills for years before starting off FASS fuel systems in 2003 - in his own garage! With a steadily growing demand from customers around the world, FASS Fuel expanded in 2014, catering to a wide range of diesel engine needs.
