Sierra Tank Connector 18-8078, 1/4 Inch NPT Male, Replaces 65740-95500, 99105-00193

The Sierra 18-8078 Tank Connector is a 1/4 inch NPT male fitting with a.508 inch outer diameter, designed to attach at the fuel tank end of a portable outboard fuel line assembly. It threads into the tank fitting and mates with the Sierra 18-8079 quick-connect fuel connector to complete the tank-to-engine fuel line connection. The male connector body allows fuel to flow from the tank through the line to the engine, and it is built to the same dimensional standard as the original equipment tank fitting it replaces, so it installs and seals the same way as the OEM part. This connector fits all models within its application and is a direct cross-reference for the OEM part numbers listed below, making it a straightforward replacement when a tank connector has cracked, worn out, or is missing from a fuel line kit. Because it mates specifically with the 18-8079 fuel connector (a separate part), buyers assembling or repairing a complete fuel line should confirm they have the correct mating half for their setup.
