Sierra Fuel Connector 18-80415, Replaces 6E5-24305-05, for Yamaha 8mm Fuel Line

The Sierra 18-80415 is a small fuel connector engineered to mate with Yamaha 8mm fuel line, forming a secure coupling point in the outboard fuel system. Machined from anodized aluminum, it provides a durable, corrosion-resistant connection between the fuel line and the engine or portable tank fitting. This connector mates with Sierra fitting 18-8077-1, allowing it to complete a proper fuel line coupling for Yamaha outboard applications.

Its compact 5.75 x 2 x 1.5 inch size and 0.07 pound weight make it an easy, low-cost swap for a worn, cracked, or leaking factory connector. The anodized aluminum body resists fuel exposure and marine environments, and the coupling-type connector design ensures a tight, reliable seal when paired with the correct mating fitting. This part directly replaces the original Yamaha fuel connectors listed below, so it is a straightforward drop-in fix for fuel line connection issues on compatible Yamaha outboards.
