Sierra Fuel Connector 18-80419, Replaces 65720-986B0, Fits Suzuki DF25-DF140 Outboards

The Sierra 18-80419 is a 5/16 inch fuel connector fitting built for Suzuki DF25-DF140 outboard fuel systems. It serves as the quick-connect fitting in the fuel line circuit, letting the fuel hose join and disconnect from the engine or tank side without tools, which simplifies routine maintenance, hose replacement, and engine winterization. The connector measures 0.39 x 0.39 x 0.39 inches and is finished in white. It is designed to mate with companion connector 18-80404, so the pair forms a complete matched fuel line connection set on applicable Suzuki outboard installations. As a direct-fit replacement for the OEM Suzuki fitting, it restores a tight, leak-free seal in the fuel line where the original connector has worn, cracked, or lost its sealing ability. Because fuel connectors see constant handling and exposure to ethanol-blended fuels, replacing a worn unit with the correct Sierra part helps prevent fuel leaks, poor engine starting, and fuel delivery problems caused by a failed seal at the connection point.
