Parts Desk Insights
The single most important check with this fitting is size — 10mm (8M6002065) vs. 5/16" (8M6002064). Mercury uses both in very similar fuel-supply assemblies on EFI FourStroke outboards, and they are not interchangeable. Any fuel leak at a quick-connect fitting is a fire hazard and should be addressed immediately. Always confirm against the engine’s fuel system diagram before selling either fitting.
