Troubleshooting & FAQ
How do I know if this fitting is correct for my engine?
The best way to confirm is by matching your old part number to one of the cross-references provided (e.g., 22-13563A3, 22-13563Q3, 18-8076). Additionally, check the compatibility table for your engine's model, HP, and serial number range.
What are the signs of a failing fuel line connector?
Common symptoms include fuel leaks at the connection point, difficulty starting the engine, a strong smell of gasoline, or the engine stalling. A connector that is cracked, brittle, or does not click securely into place should be replaced immediately.
Is this a tank-side or engine-side connector?
This is an engine-side female connector. It is designed to clip onto the male fuel inlet fitting located on the outboard motor itself.
How often should fuel line connectors be replaced?
There is no fixed replacement interval. Connectors should be inspected regularly as part of routine maintenance and replaced at the first sign of wear, damage, or leakage to prevent fuel system issues.
What is the difference between this and the OEM part?
This is an aftermarket part designed to meet or exceed OEM specifications for fit, form, and function. It offers comparable performance and material quality at a better value.
Can I use this with ethanol-blended fuels?
Yes, this connector is made from modern materials compatible with standard marine gasoline, including ethanol-blended fuels like E10. However, always inspect fuel system components regularly when using ethanol blends.
