Installation Guide

1. Safety First: Turn off the engine and allow it to cool completely. Work in a well-ventilated area away from open flames or sparks.
2. Locate Connector: Identify the existing fuel line connector on the outboard engine.
3. Prepare for Spillage: Place a rag or absorbent cloth under the connector to catch any residual fuel.
4. Disconnect Old Fitting: Firmly depress the release mechanism (clip or tabs) on the old connector and pull it straight off the engine fitting.
5. Inspect New Connector: Before installation, check the new connector for any signs of damage or debris.
6. Install New Connector: Align the new female connector with the male fitting on the engine and push it on firmly until you hear or feel it "click" into place.
7. Confirm Connection: Gently tug on the fuel line to ensure the connector is securely locked onto the engine fitting.
8. Check for Leaks: Prime the fuel bulb until it becomes firm. Carefully inspect the connector and surrounding area for any signs of fuel leakage.
