THANK YOU FOR A QUICK REPLY , I HAVE YET TO LIFT THE CAR IN THE AIR TO IDENTIFY THE PROBLEM, I HAVE NOTICED THE SMELL AND LOOKED UNDER the car to see where it could be leaking , right now I see it leaking at thee rear of the tank by the 2nd muffler. and the side by the fillling tube. I am lucky enough to have a parts guy at mercedes give me a blowup dissected views of the fuel system and from what i can read it seams as though there is no lines or fittings that could be loose,at the rear of the tank
i have posted this at another forum and have been directed to
http://www.gastankrenu.com/.
I really appreciate the link and i wll establish where the leak is before buying any parts of course.
I still am having a hard time locating any other source of fuel tanks (rebuilt or new
aftermarket).
I will look into this repair a gas tank site and gather more info .
