Product Details
This marine-grade 1/4-inch (6 mm) fuel line assembly with primer bulb is designed for portable fuel tank-to-engine connections on a wide range of Yamaha outboard applications from 4 to 350 HP. It may be used with applicable 2-stroke and 4-stroke engines when the connector style, hose size and reference number match the original equipment.
The assembly is listed as a replacement for several Yamaha fuel-line references, including 6YL-24306-68, 6Y1-24306-55 and 61J-24306-04. Always compare the connectors and existing part with the applicable engine or fuel-tank service information before installation.
- Fuel hose assembly with an integrated primer bulb for manual fuel priming.
- Pre-attached quick-connect fittings for compatible portable tank and outboard connections.
- Flexible rubber construction described for resistance to UV exposure, ozone and alcohol-blended fuel.
- Suitable as an aftermarket replacement when the dimensions and connector configuration match the original assembly.

- Install the assembly with the arrow on the primer bulb pointing from the fuel tank toward the engine.

- Squeeze the primer bulb several times until it becomes firm, then inspect every connection for leakage before starting the engine.
Troubleshooting and FAQ
Will this fuel line fit every Yamaha outboard?
No single fuel-line assembly fits every Yamaha configuration. This assembly is listed for a broad 4–350 HP range, but exact fitment depends on the engine model, year, serial range, stroke type, tank connection and connector style. Compare the reference numbers and fittings with the original assembly before purchase.
What indicates that a fuel line needs replacement?
Common signs include cracked or hardened hose material, fuel seepage around the hose or connectors, a primer bulb that will not remain firm, air entering the fuel system, sputtering or stalling. Stop using any line that leaks or shows deterioration.
Can it be used with ethanol-blended gasoline?
The hose is described as resistant to alcohol-enhanced fuel and is intended for common ethanol-blended gasoline such as E10. Use clean, approved marine fuel and replace the line if swelling, softening, cracking or leakage develops.
How should the primer bulb be oriented?
Install the primer bulb with its arrow pointing toward the engine. Squeeze it repeatedly until firm to draw fuel from the tank toward the engine before starting.
Is this an OEM part?
This is an aftermarket replacement assembly. The listed Yamaha numbers are manufacturer reference numbers used for comparison and identification; the assembly is not represented as a Yamaha-branded OEM component.
What should I check before ordering?
Check the hose inner diameter, overall length, bulb direction, connector shape and the exact reference number. For model-specific applications, also confirm the engine year, serial range and stroke type using the applicable service documentation.
What are the shipping and warranty terms?
Shipping options, delivery estimates, warranty coverage and return eligibility are determined by the applicable order and store policies. Review the current policy information at checkout or contact support before ordering if these terms are important to your purchase.
Safety and Important Information
- Work in a well-ventilated area away from flames, sparks and ignition sources.
- Verify the connectors, hose size, reference numbers and physical configuration against the original part before installation.
- Do not operate the engine if any fuel connection leaks or the hose is damaged.
- This is an aftermarket replacement, not a Yamaha OEM component.
- Professional installation is recommended when you are not familiar with marine fuel-system service.
