If you see the error message in your car saying “Tighten fuel cap”, “Tighten gas cap”, or “Check fuel cap”, there is a high chance that this has nothing to do with the fuel cap itself. In most cases, the EVAP system will be in charge and solving this problem on your own is not that easy.
In this video, I will tell you about several most common reasons for these warnings to come on the dash of your car. And will also offer the solutions you may try on your own.
It’s important to react immediately whenever you see such a message because it may result in fuel leaking out of the tank or your engine working incorrectly due to poor air supply through the broken purge valve. So, take it seriously!
