Thanks. I will check mine when I get a chance and I will relay this to him as well.

Someone told me if it was leaking then the car may be hard to start... my car is easy to start and AFAIK, his is as well.

I am starting to panic because my Lexus has broken and I may need to start driving the MB regularly and dont want to if there is a fuel leak issue.

I guess its not like it spews gas or anything does it? I cant be losing much fuel, as I get about 20-21 mpg in city driving. As mentioned, the smell is so minor, I was thinking it was just fumes coming from the air cleaner housing.
