The key phrase is that there are no leaks visible.

There is an extensive network of vapor recovery tubes that run on top of the fuel tank and those have been known to be a problem. Also, if there has been any aftermarket audio work done it isn't uncommon to see an installer actually drill into the fuel tank while drilling holes for screws.

Unfortunately, to make a complete evaluation of fuel vapors coming from that area the best way is to break down and pull the fuel tank for inspection of the tank and associated lines.
