Product Details
This aftermarket Fuel Line Connector Kit is designed as a replacement connection set for a broad range of Yamaha outboard engines rated from 6 to 90 HP. The kit includes one male and one female quick-connect fitting for replacing worn, damaged or leaking fuel-line connectors between the fuel tank and engine.
The connectors are marketed as replacements for Yamaha reference numbers 6Y1-24305 and 6G1-24305, with Sierra aftermarket references 18-80414 and 18-80413. Always compare the connector style and the part number on your original components before ordering, because compatibility can vary by engine model, production year and fuel-system configuration.
- Includes one male and one female quick-connect fuel-line fitting.
- Designed for direct replacement when the original connector configuration matches.
- Suitable for gasoline fuel systems, including systems using ethanol-blended fuel when compatible with the application.
- Check the original connector and service information before installation.

Installation Notes
- Turn the engine off, allow it to cool and work in a well-ventilated area away from ignition sources. Relieve fuel-system pressure as appropriate for the application.
- Disconnect the original fuel line from the engine and fuel tank, and inspect the hose, fittings and sealing surfaces for damage.
- Cut the fuel hose cleanly only if the connector is a hose-mounted replacement and the hose remains suitable for reuse.
- Install the female connector on the fuel-tank side and the male connector on the engine side only when this matches the original configuration.
- Secure the connectors with suitable fuel-line clamps where required. Do not overtighten or damage the hose.
- Reconnect the fittings and confirm that each quick-connect fitting locks fully into place.
- Prime the fuel system and inspect every connection for leaks before starting the engine. Do not operate the engine if any fuel leakage is present.
Troubleshooting and FAQ
How do I confirm fitment for my Yamaha outboard?
Compare the connector shape, connection size and orientation with the original part, then check the engine model, year and serial-number information in your owner’s or service manual. The listed Yamaha reference families are 6Y1-24305 and 6G1-24305, but these references alone may not confirm every application.
What are common signs that a fuel-line connector needs replacement?
Common signs include fuel leakage, air entering the fuel line, difficulty priming, hard starting, stalling, a loose connection, visible cracking or deterioration, and a fitting that does not lock securely.
Are special tools required?
Installation generally requires basic hand tools and a suitable hose cutter or sharp utility knife if the hose must be cut. Use only clamps and fuel-system components suitable for the application.
Can this kit be used with ethanol-blended gasoline?
The kit is intended for gasoline fuel-line applications, but fuel-system compatibility depends on the complete hose and connector assembly. Confirm that the connectors, hose and clamps are suitable for the fuel used in your application, including ethanol-blended gasoline.
Can I purchase only the male or female connector?
This listing is for a kit containing one male and one female connector. Confirm the package contents before ordering if you need only one side of the connection.
Is this an OEM Yamaha part?
No. This is an aftermarket replacement kit intended to replace compatible Yamaha and Sierra-referenced fuel-line connectors. It is not manufactured by Yamaha or Sierra.
How fast is shipping and what does it cost?
Available shipping methods, delivery estimates and shipping charges are shown at checkout and depend on the destination and selected service.
What is the warranty and return policy?
Warranty and return eligibility are governed by the current store policy. Contact support with your order details before returning an item, and do not install or operate a component that appears damaged or incorrect.
Safety and Important Information
- Fuel is flammable. Work in a well-ventilated area away from sparks, flames and other ignition sources.

- Inspect all fuel-line components after installation and check carefully for leaks before operating the engine.
- This is an aftermarket replacement part and is not an original equipment manufacturer component.
