Sierra 18-8056 Fuel Connector, Replaces OMC 174508 775640, Johnson/Evinrude

The Sierra 18-8056 is a quick-connect fuel connector designed for Johnson/Evinrude outboard fuel systems. It provides a secure, leak-resistant coupling point in the fuel line, allowing fast connection and disconnection of the fuel supply without tools. The fitting uses a quick-connect style inlet, letting boaters attach or detach the fuel line hose end quickly for maintenance, winterization, or engine removal. This connector is designed to mate with the Sierra 18-8063 fitting to complete a matched connector set, ensuring a proper seal between the two halves of the fuel line coupling.

Built to replace OEM Johnson/Evinrude (OMC) fuel connectors, the 18-8056 is a direct-fit replacement part for boat owners performing routine fuel system repairs or upgrades. Its compact size keeps it unobtrusive in tight engine compartments, and its automatic operation mode means it seals the fuel line automatically when disconnected, reducing spills during servicing.
