Replacement bowl for Yamaha fuel filter/water spearators For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters and techs can be assured a Sierra part will fit right the first time and restore function to OEM standards. This replacement bowl is designed to work with Yamaha outboards equipped with a fuel filter/water separator. The coated metal construction provides corrosion resistance and gives the bowl the ability stand up to heat. A drain plug allows users to safely remove water and debris to extend the life of the filter.
