That could very well be the "O" ring seal at the top of the tank.

Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 29+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

I would have to agree with Jerry. Since you only get the smell on a full tank, I suspect that the fuel is leaking through the o ring that seals the fuel pump to the tank. This will ALSO cause a check engine light due to an EVAP System Large Leak...

The fix is to replace the fuel pump o ring or properly install it. After that clear all codes and all should be well...

Keep me posted and let me know if you have any additional questions...

Thank you,

Robert
