Installation Guide
-
Safety First: Before starting, disconnect the boat's battery and ensure you are working in a well-ventilated area away from any open flames or sparks.
-
Locate Connector: Identify the existing engine-side fuel connector on your Yamaha outboard motor.
-
Relieve Pressure: Carefully relieve any pressure from the fuel line. Place a rag or absorbent pad under the connector to catch any gasoline drips.
-
Disconnect Old Part: Press the release tabs on the old connector and pull it straight off the fuel fitting.
-
Inspect Fuel Line: Check the fuel line hose for any signs of cracking, brittleness, or other damage. Replace the entire fuel line assembly if it appears worn.
-
Install New Connector: Push the new fuel connector firmly onto the engine's fuel fitting until you hear or feel it click securely into place.
-
Reconnect Fuel Line: Attach the fuel line to the new connector.
-
Prime System: Squeeze the primer bulb repeatedly until it becomes firm, indicating that the fuel system is primed.
-
Check for Leaks: With the system pressurized, visually inspect the new connector and all fittings for any signs of fuel leakage.
-
Final Checks: Reconnect the battery. Start the engine and let it run for a few minutes while re-inspecting the connector to ensure there are no leaks under pressure.
