Troubleshooting & FAQ
How can I confirm this connector fits my specific Yamaha engine?
The best method is to match the part number from your old connector to one of the numbers listed in our Part Number Matrix (e.g., 6G1-24305-04). While this part fits a wide range of 6-90 HP motors, checking the OEM part number is the most reliable way to ensure compatibility.
Is this for the engine side or the fuel tank side?
This is a female connector designed specifically for the engine side of the fuel line. It mates with the male fitting on your Yamaha outboard motor.
What are common signs that my fuel connector needs replacement?
Symptoms of a failing fuel connector include fuel leaks at the connection point, air entering the fuel line (causing the engine to sputter or stall), difficulty starting, and a loose or cracked physical connection.
Will this work with non-Yamaha engines?
This connector is specifically designed to meet the specifications for Yamaha outboards and aftermarket parts that cross-reference Yamaha P/N 6G1-24305. We do not recommend using it for other engine brands, as the fitting dimensions may be incompatible and could lead to fuel leaks.
What is the difference between this aftermarket part and the OEM version?
Our aftermarket parts are engineered to meet or exceed OEM specifications for fit, form, and function. They are made with comparable, high-quality materials in an ISO 9002 certified facility and undergo rigorous quality control. The primary difference is the price, offering a cost-effective solution without compromising on reliability.
How fast is shipping and what does it cost?
We ship worldwide, with most orders arriving in 5–15 days via standard shipping. Standard shipping is free. If available for your location, expedited shipping options and costs will be displayed at checkout.
What is your warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal marine use. If you encounter an issue, please contact us with your order details. We accept returns for unused items in their original packaging within our standard return window. Please see our full policy page for more details.
