Installation Notes

  1. Ensure the engine is off and cool. Work in a well-ventilated area away from sparks or open flames.
  2. Disconnect the old fuel line from the fuel tank and the outboard motor. Have a rag ready to catch any minor fuel spillage.
  3. Inspect the fuel connectors on the tank and engine for dirt or damage. Clean as necessary.
  4. Attach the new fuel line assembly. The arrow on the primer bulb should point in the direction of fuel flow (from the tank to the engine).
  5. Secure the line to the fuel tank and engine connectors using the provided hose clamps. Ensure a tight, leak-proof seal.
  6. Squeeze the primer bulb until it becomes firm, which indicates fuel has filled the line.
  7. Check for any leaks at all connection points before starting the engine.

Troubleshooting & FAQ

How do I know if this fuel line will fit my motor?

This is a universal fuel line designed for a 5/16" (8mm) connection. It's compatible with most outboard motors from brands like Yamaha, Suzuki, Tohatsu, Honda, and more, typically in the 2-200 HP range. Always verify your motor's required fuel line inner diameter before ordering.

The arrow on the primer bulb is important. Which way should it point?

The arrow on the primer bulb indicates the direction of fuel flow. It must always point from the fuel tank towards the engine for the fuel system to work correctly.

What are the signs that my old fuel line needs replacement?

Common signs include visible cracks, brittleness, or leaks in the hose. A primer bulb that won't stay firm or takes a long time to prime can also indicate failing internal check valves, signaling it's time for a replacement.

Is this fuel line compatible with ethanol-blended fuels?

Yes, this fuel line is constructed with modern, ethanol-resistant materials to prevent degradation and maintain fuel system integrity with today's E10 and E15 gasoline blends.
