Installation Guide

1. Turn off the engine and disconnect the battery to ensure safe working conditions. Allow the engine to cool completely before starting.
2. Locate the water separator assembly on your Honda outboard engine. Refer to your engine's service manual or parts diagram if needed.
3. Relieve fuel system pressure by loosening the fuel line connection slightly. Have a rag ready to catch any residual fuel.
4. Remove the water separator bowl by turning it counterclockwise. Drain any remaining fuel into an approved container.
5. Remove the old fuel filter element from the separator assembly. Inspect the housing and O-rings for wear or damage.
6. Clean the separator bowl and housing thoroughly with a lint-free cloth. Ensure no debris remains inside.
7. Install the new 16910-ZY9-004 fuel filter element into the separator housing, ensuring proper seating.
8. Reinstall the separator bowl, tightening it by hand until snug. Do not over-tighten to avoid cracking the bowl.
9. Reconnect fuel lines securely and check all connections for proper fit. Ensure clamps are tight.
10. Reconnect the battery and turn the ignition to the "on" position without starting the engine. This primes the fuel system.
11. Check for fuel leaks around the separator assembly and connections. If leaks are present, turn off the engine and re-tighten connections.
12. Start the engine and allow it to idle for several minutes. Monitor for smooth operation and recheck for any fuel leaks.
