Installation Guide

1. Safety first: Disconnect the fuel line and ensure no fuel is present in the work area. Work in a well-ventilated space away from ignition sources.
2. Locate the old fuel cock assembly on your Mariner outboard motor. It is typically positioned between the fuel tank connection and the carburetor.
3. Remove the fuel lines connected to the existing fuel cock switch. Use a container to catch any residual fuel.
4. Unscrew or unclip the old fuel cock assembly from its mounting position. Note the orientation and positioning for proper reinstallation.
5. Position the new fuel cock assy switch in the same orientation as the original part. Ensure all mounting points align correctly.
6. Secure the new switch using the original mounting hardware or new fasteners if necessary. Tighten firmly but do not over-torque.
7. Reconnect the fuel lines to the appropriate inlet and outlet ports on the new fuel cock switch. Ensure connections are snug and secure.
8. Check for leaks: Turn the fuel cock to the ON position and inspect all connections for fuel leakage. Wipe dry and observe for several minutes.
9. Test operation: Cycle the fuel cock switch between ON and OFF positions several times to confirm smooth operation and proper fuel flow control.
10. Start the engine and allow it to run for a few minutes. Monitor for proper fuel delivery and any signs of leakage or malfunction.
