Troubleshooting & FAQ
Q: How do I confirm this kit fits my Yamaha engine?
A: This kit is designed for most Yamaha 6 HP to 90 HP 2-stroke and 4-stroke outboards. To ensure a perfect match, please check the "Compatible Engine Models" table and cross-reference your engine's original part numbers with those listed in our "Part Number Cross-Reference" table.
Q: What are the signs of a failing fuel line connector?
A: Common signs of failure include visible fuel leaks at the connection point, a persistent smell of gasoline, difficulty starting the engine, or stalling at low speeds. Cracked, faded, or brittle plastic on the original connectors are also clear indicators that a replacement is needed.
Q: How often should I inspect or replace the fuel line connectors?
A: We recommend visually inspecting your fuel line connectors at the start of each boating season and before long trips. There is no fixed replacement interval, but they should be replaced immediately if you notice any signs of wear, damage, or fuel leakage. This is especially important if you regularly use ethanol-blended fuels, which can accelerate material degradation.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details.
