Troubleshooting & FAQ
How do I know if my VST seal is failing?
Common signs include fuel leaks around the vapor separator tank, a strong smell of gasoline, or engine performance issues like stalling, hard starting, or rough idling, especially at low speeds.
Will this seal fit models outside the 2001–2013 year range?
This seal is specifically designed for the Suzuki DF90–DF140 models manufactured between 2001 and 2013. Using it on other models or years is not recommended, as fitment may differ. Always verify the required OEM part number (15626-90J00) for your specific engine serial number.
What is the recommended replacement interval for this seal?
There is no fixed replacement interval. The seal should be inspected during routine fuel system service and replaced immediately if it appears hard, brittle, cracked, swollen, or is leaking.
Is any sealant required when installing this VST seal?
No, this seal is designed to create a secure fit on its own. Do not use any additional liquid gaskets or sealants, as they can interfere with proper sealing or degrade the rubber material.
