I was doing a walk around of an 05 E55 and noted a pretty strong smell of gas after the car had been test driven. This was about 10 minutes after the car was parked. Is this the first sign of a fuel tank/sender problem? The dealer noted the smell too.

 

Lots of info all over the net.

Also some good DIY on the repair.
