Troubleshooting & FAQ

Q: How do I know if this connector will fit my Johnson/Evinrude engine?

A: This connector is designed for Johnson/Evinrude outboards that use a 5/16" fuel line. Please verify your fuel line size and compare your existing connector to the images and cross-referenced part numbers (174508, 176745, 775640) to ensure a match.

Q: What causes a fuel line connector to fail?

A: Failure is often due to a degraded or cracked internal O-ring, which leads to air leaks and fuel delivery problems. Physical damage from impact or material fatigue from age and ethanol exposure can also cause the housing to crack or fail.

Q: Is this a male or female connector?

A: This is a female quick-disconnect connector that attaches to the fuel line. It mates with the male connector on the engine or fuel tank side (such as part 18-8063).
