Troubleshooting & FAQ

How do I confirm this fuel line fits my specific Yamaha engine?
This assembly fits a wide range of Yamaha outboards from 4 to 350 HP. The best way to ensure compatibility is to match your old part number with the cross-reference numbers on this page, such as 6Y1-24306-55.

What are the signs that my fuel line needs replacement?
Common symptoms include visible cracks or brittleness in the rubber hose, fuel leakage at the connectors or primer bulb, a bulb that will not become or stay firm, or poor engine performance like stalling and hesitation due to restricted fuel flow.

How often should I replace my outboard fuel line?
We recommend inspecting your fuel line annually for any signs of wear, such as cracks, stiffness, or leaks. For preventative maintenance, consider replacing the assembly every 2-3 years, especially if your boat is operated in saltwater or exposed to prolonged direct sunlight.
