I just removed the fuel door assembly to remove the gastank. Upon reinstallation, I can't seem to get the fuel door to sit flush with the body, or open without slightly rubbing the quarter panel. It does not look like there is any room for adjustments. Any ideas on how to make the fuel door fit flush with the quarter panel? Thanks!!

 

Real common problem. So much so, there is a tech article about it.

Awesome! Mines rubbing too.

 

Cool

 

You could be missing the gasket that goes under it.
