Installation Notes

  1. Ensure the engine is off and the work area is well-ventilated. Disconnect the battery for safety.
  2. Carefully disconnect the old fuel line from both the fuel tank and the outboard motor. Have a rag ready to catch any residual fuel.
  3. Attach the new fuel line assembly. Connect the appropriate end to the fuel tank's outlet.
  4. Connect the other end of the fuel line to the motor's fuel inlet. Ensure both quick-connect fittings click securely into place.
  5. Squeeze the primer bulb repeatedly until it feels firm, indicating that fuel has filled the line.
  6. Inspect the entire line, primer bulb, and all connection points for any signs of leaks before starting the engine.

Troubleshooting & FAQ

How do I confirm this fuel line fits my engine?

Check the Part Number Matrix for cross-references and review the Engine & Model Compatibility tables. It's crucial to match your engine's brand, model, horsepower, and year range.

Is this hose compatible with modern ethanol-blended gasoline?

Yes, this fuel line assembly is constructed with materials designed to resist degradation from ethanol-blended fuels like E10.

What are the signs that my old fuel line needs to be replaced?

Common signs of failure include visible cracks, brittleness, a primer bulb that won't stay firm or is slow to return to shape, and fuel leaks or odors around the hose and fittings.

How often should a marine fuel line assembly be replaced?

There is no fixed interval, but regular inspection is key. We recommend replacing it every few years as preventative maintenance or immediately if you notice any signs of wear, damage, or leaks.

The primer bulb feels soft and won't prime the engine. What should I do?

Ensure the arrow on the primer bulb is pointing in the direction of fuel flow (from the tank to the engine). Check that all connections are airtight and that the fuel tank is properly vented. A soft bulb may indicate a leak in the line or a faulty check valve.

Can I cut this hose to a shorter length?

We do not recommend modifying the assembly. Cutting the hose would require re-installing the end fittings, which can compromise the seal and lead to dangerous fuel leaks if not done professionally.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). It has been built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, it is batch-inspected for consistency.
