Re: [MBZ] Help

Are you *sure* there isn't a leak?  I had one on my Volvo that only 
leaked when the engine was running, and it was in an area where the fuel 
could pool and evaporate instead of dripping to the ground.  It took 
running the car while it was on the rack to find it.  After repairing 
it, the fuel smell persisted for a week or so because the undercoating 
was saturated with gasoline.

If you're sure it's not leaking, I'd start looking for a loose fuel tank 
vent line, bad fuel tank filler neck seal, or rust holes in the top of 
the tank.  These are generic suggestions because I don't know your 
particular car at all.
