Technical Specifications

Package Contents

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

Installation Guide

1. Ensure the engine is off and the work area is well-ventilated.
2. 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.
3. Attach the new fuel line's engine-side connector to the motor's inlet. You should hear a 'click' sound, indicating a secure fit.
4. Attach the tank-side connector to the fuel tank outlet, ensuring it also clicks securely into place.
5. Squeeze the primer bulb repeatedly, with the arrow pointing in the direction of fuel flow (towards the engine), until it becomes firm.
6. Visually inspect all connection points and the entire length of the hose for any signs of fuel leaks.
7. 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.
