Technical Specifications

Package Contents

• 1 × Fuel Line Assembly with Primer Bulb (6 feet long)
• 2 × Stainless Steel Hose Clamps

Installation Guide

1. Ensure the engine is off and cool. Place a drip pan or absorbent rags under the connection points to catch any spilled fuel.
2. Disconnect the old fuel line from the engine and the fuel tank. Be prepared for a small amount of fuel leakage.
3. Attach the new fuel aine assembly. The arrow on the primer bulb should point in the direction of fuel flow (from the tank to the engine).
4. Secure the hose to the fuel tank and engine fittings using the provided stainless steel clamps. Ensure clamps are tight but do not overtighten.
5. Squeeze the primer bulb until it feels firm to draw fuel from the tank and fill the line.
6. Check all connections for any signs of leaks. Address any leaks immediately.
7. Start the engine and allow it to run for a few minutes while continuing to inspect for leaks.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?

A: This is a universal fuel line for applications requiring a 3/8" (10mm) inner diameter hose. It is a direct cross-reference for Yamaha part 6Y2-24306-05-00. Always measure your existing fuel line's inner diameter and check your engine's part manual to confirm compatibility.

Q: My primer bulb won't get firm or the engine is stalling. What's wrong?

A: First, ensure the arrow on the primer bulb is pointing in the direction of fuel flow (towards the engine). An incorrect orientation will prevent fuel from being pumped. Second, check for air leaks at the connection points; ensure clamps are tight. A cracked or old fuel tank pickup tube can also introduce air into the system.

Q: How often should I replace my marine fuel line?

A: Fuel lines should be inspected regularly for signs of cracking, stiffness, brittleness, or swelling. As a general guideline, consider replacing fuel lines every 2-5 years, depending on usage, exposure to sunlight, and fuel type (ethanol blends may accelerate wear).
