Troubleshooting & FAQ
How do I know if this connector fits my engine?
This connector is designed for Mercury, Mariner, and Force outboards from 4-40 HP that use a clip-on style fuel connector at the tank. Please visually compare it to your existing part and check the compatibility table to confirm fitment.
What is the difference between the tank-end and engine-end connector?
This is a tank-end (female) connector that attaches to the portable fuel tank. The engine-end connector is a different part. Ensure you are replacing the correct fitting for your application.
What are the signs of a failing fuel connector?
Common signs include fuel leaks around the fitting, difficulty connecting or disconnecting, a loose fit, or air entering the fuel line, which can cause the engine to stall or run poorly. The double-sealed design helps prevent these issues.
Can I use this with ethanol-blended fuels?
Yes, this connector is designed for use with standard marine gasoline, which may include ethanol blends (up to E10). Always follow your engine manufacturer's fuel recommendations for best performance and longevity.
How often should fuel line connectors be replaced?
There is no fixed replacement interval. Inspect connectors regularly for cracks, leaks, or material degradation, especially at the start of each boating season. Replace them immediately if any damage or leaks are found to prevent fire hazards.
