The FASS STK-5500 Fuel Sump Kit is designed to be capable of functioning independently or in combination with our Fuel Air Separation System, drivers can now get the benefits that come with a sump but without any of the inherited issues.

Like most sumps on the market, the FASS Sump Kit can pull fuel from the outside of the sump through a pre-tapped 1/2" fuel port.
