Sierra Fuel Connector 18-80418, Motor Side, Replaces 65720-94401, Fits Suzuki DT4-DT65 Outboards

The Sierra 18-80418 is a motor-side fuel connector engineered for Suzuki DT4 through DT65 outboard engines. This fitting is the connection point where the fuel line attaches to the engine, using a 1/4 inch barb to secure a standard fuel hose. It is built as a direct replacement for the original Suzuki fuel connector, letting you restore a tight, leak-free fuel supply connection without sourcing OEM parts through a dealer.

Fuel connectors are a common wear item since they see constant handling every time the fuel line is connected or disconnected, and the internal seals and check valve components degrade with age and ethanol-blended fuels. Replacing a worn or leaking connector at the engine side restores proper fuel flow and prevents air intrusion or fuel leaks at the connection point. The 18-80418 is sized specifically for the motor side of the fuel line circuit, distinct from the fuel tank side connector, so it should be installed at the engine end of the fuel line only.
