Mercury/Mariner Male Fuel Connector 9.2 mm (Engine Side, 3/8")

This 9.2 mm male fuel connector is intended for Mercury and Mariner outboards that utilize a larger fuel hose (3/8") to meet their fuel needs. It attaches to the engine’s fuel inlet and serves as the quick-connect point for the fuel line. Thanks to its wider opening, this connector permits increased gasoline flow – critical for higher horsepower engines or when running at full throttle.

The connector uses Mercury/Mariner’s standard quick-lock mechanism: when the hose’s female connector is attached, it locks in place via pins and holds the hose securely. With a 9.2 mm barb, it’s optimal for hoses of ~9.5 mm inner diameter (3/8"), commonly found on engines of 60, 90, 150 HP and above. The construction is geared towards durability – the connector remains stable under heavy vibration and pounding waves. Materials are chosen for the marine environment: a tough plastic body that won’t crack from UV or fuel exposure, and stainless steel springs to ensure secure locking.

• For Fuel-Hungry Engines: If your Mercury/Mariner motor is a larger model or a V6, it consumes fuel at a higher rate. This 9.2 mm connector ensures the fuel flow won’t be choked by an undersized fitting. It helps prevent the engine from “running lean” at high RPMs – your engine gets all the fuel it needs for maximum power.
• Improved Performance: Even on mid-range engines (e.g. 50–90 HP), upgrading to this larger connector can contribute to smoother operation, especially if you’ve tuned or upgraded other components (like carburetion/fuel injection). The enhanced fuel throughput removes potential bottlenecks and sets the stage for optimal performance.
• Secure in Extreme Conditions: Operating your boat in rough water and at high speeds demands parts you can trust. This connector is engineered to stay locked and sealed no matter the pounding from waves. It boosts safety – no risk of the hose shaking loose during heavy slamming or high vibration.
• Compatibility & Installation: The connector fits all Mercury/Mariner models that use the clip-on style. It can easily install in place of an older 8 mm connector if you choose to upgrade. The result is the same easy operation but with higher fuel capacity through the line.
