Product Details
This is an aftermarket replacement Yamaha fuel line connector for applications using a 1/4-inch fuel connection. It is listed as a replacement for Yamaha fuel connector references 6G1-24305-04 and 6G1-24305-05-00, and is cross-referenced with Sierra 18-80414.
The connector is intended to provide a secure connection between compatible Yamaha outboard fuel-system components. Because Yamaha used different connector designs across engines, fuel lines, and model years, confirm the existing connector, fuel-line size, and applicable part number before ordering.
- Aftermarket replacement for a Yamaha fuel connector.
- Designed for compatible 1/4-inch fuel-line applications.
- Quick-connect style fitting for straightforward replacement when the original connector and application match.
- Verify the connector profile and part number before installation.
Part Number Matrix
Use the following references to compare the replacement connector with your original part.
| Brand | Part Number | Reference Type |
|---|---|---|
| Yamaha | 6G1-24305-04 | Replacement reference |
| Yamaha | 6G1-24305-05-00 | Replacement reference |

Engine & Model Compatibility
This connector is associated with Yamaha outboard fuel-system applications using the listed Yamaha references. The available catalog evidence does not establish one unrestricted fitment range for every Yamaha 6–90 HP engine, so model, year, fuel-line size, and connector style must be confirmed individually.
| Brand | Application | Fuel Connection | Replacement References | Fitment Requirement |
|---|---|---|---|---|
| Yamaha | Compatible outboard fuel-system applications | 1/4-inch fuel connection | 6G1-24305-04; 6G1-24305-05-00 | Match the original connector and verify the engine model and year |

Troubleshooting & FAQ
How do I confirm this connector fits my Yamaha outboard?
Compare your original connector with the product and match the applicable reference to 6G1-24305-04 or 6G1-24305-05-00. Also verify the engine model and year, fuel-line size, connector profile, and mating fitting. Horsepower alone is not sufficient to confirm fitment.
Is this the same connector as a 6Y1-series Yamaha part?
Do not assume that 6Y1-series references are interchangeable with this connector. The documented references for this listing are Yamaha 6G1-24305-04 and 6G1-24305-05-00, together with aftermarket reference Sierra 18-80414.
What are the signs of a failing fuel connector?
Common signs include fuel odor, visible leakage, difficulty priming, hard starting, stalling, or a connector that is cracked, brittle, loose, or unable to lock securely. Stop using the engine and replace damaged fuel-system components immediately.
Should the fuel hose be replaced at the same time?
Inspect the hose whenever the connector is replaced. Replace the hose or clamps if they show cracking, swelling, hardening, abrasion, or leakage. Use components suitable for the fuel system and follow the engine manufacturer's service guidance.
Is this an OEM Yamaha component?
No. This listing is for an aftermarket replacement connector. Yamaha and Sierra part numbers are provided only as reference and cross-reference information.
What should I do if the connector does not match?
Do not force the part into place or modify the connector. Compare the original part number and connector profile, then confirm the application with the engine or boat manufacturer before installation.
