Sierra Fuel Connector 18-80403 Female 3/8 Inch White Outboard Fuel Line Fitting

The Sierra 18-80403 is a female fuel connector designed for late model outboard engines, providing a secure, leak-resistant link between the fuel hose and the engine's fuel line. It features a female connection with a rectangular locking post that clicks firmly into place, holding the mating fitting secure during engine operation and vibration. The connector is sized for 3/8 inch (95mm) fuel hose and is molded in white for easy identification against black hose and hardware. This connector is built to mate with the Sierra 18-80407 fitting and is intended for use with the Sierra 18-81042 fuel hose assembly at the motor end. Because it uses a rectangular locking post and 3/8 inch bore, it will not interchange with older OE fuel connectors that use a 5/16 inch hose assembly design, so it is important to confirm your engine's hose size and connector style before ordering. The connector ships as a single item and is a straightforward swap for boaters replacing a worn, cracked, or leaking fuel connector as part of routine fuel system maintenance. Its compact size and lightweight construction make it an easy, affordable part to keep on hand for outboard fuel system repairs.
