Package Contents
- 1 x Fuel Line Assembly with Primer Bulb (Replaces 6YL-24306-68 / 6Y1-24306-55 / 61J-24306-04)

Installation Guide
- Ensure the engine is off and the work area is well-ventilated.
- Disconnect the old fuel line from the engine's fuel inlet and the portable fuel tank. Have a rag ready to catch any minor fuel drips.
- Attach the new fuel line's engine-side connector to the motor's inlet. You should hear a 'click' sound, indicating a secure fit.
- Attach the tank-side connector to the fuel tank outlet, ensuring it also clicks securely into place.
- Squeeze the primer bulb repeatedly, with the arrow pointing in the direction of fuel flow (towards the engine), until it becomes firm.
- Visually inspect all connection points and the entire length of the hose for any signs of fuel leaks.
- Once you have confirmed there are no leaks, you can safely start the engine.
Troubleshooting & FAQ
Q: How do I know if this fuel line will fit my Yamaha outboard?
A: This assembly is designed for a wide range of Yamaha outboards from 4 HP to 350 HP (both 2-stroke and 4-stroke models). The best way to confirm fitment is to check that your engine's original part number is listed in our Part Number Cross-Reference table. Also, verify that your engine uses 1/4" (6mm) inner diameter fuel line.
Q: Is this fuel line resistant to modern ethanol-blended fuels?
A: Yes. The hose is constructed from a high-quality, alcohol-enhanced fuel-resistant rubber compound that is specifically designed to prevent premature drying and cracking when used with E10, E15, and other ethanol-blended fuels.
Q: What are the signs that my fuel line needs to be replaced?
A: Common signs of a failing fuel line include visible cracks or brittleness in the hose, fuel leaks at the connectors or bulb, a primer bulb that will not stay firm, or frequent engine stalling and performance issues related to fuel starvation.
