Hi there. If you’re experiencing a fuel leak only after the fuel tank is full, then it might be one of three issues. First, it could simply be overflow caused by overfilling the tank, second it could be a damaged fuel tank filler housing or third and most likely, the fuel cap is damaged. Replacing the fuel cap is very easy, just make sure you purchase an OEM (original equipment) replacement fuel cap. If you need any help with this, one of our local mechanics can help you replace the fuel cap.
