| yeah, we just had a similar problem with one of our track e36's. Since the car had been completely stripped down, the problem was easy to find. The smell of gas was fairly strong, especially inside the car and more so, when the engine was running. It ended up being one of the fuel lines located under the back passenger seat. To access this without a lift, just take off your lower back seat portion and remove the two big round caps. You should be able to see two rubber lines going from one side to the other. Since I didn't fix the problem myself, I don't know exactly where the leak was, but I do know that we replaced those lines and the problem was fixed. The lines might be a little tricky to get out since the metal covers most of the area of the line. I hope this helps.

AMG can't build an NA engine that can compete with M engines, so they stick in a supercharger and say their cars are faster. BMW could simply do the same, but they don't out of principle.</span> | 
: I had the same problem fuel smell in the car and low and behold! the problem was right under the backseat! there was a slight crack in the cover of the fuel line connectors. Kinda of complex to fix take to a mechanic.
