<< I noticed a small leak at the manual fuel shut-off on my E300D. It seeps at the valve stem. Could that be a leaking o-ring at the filter or am I looking at replacing the valve? >>
Hans: When I had that same problem, I learned that you have to replace valve. Apparently the valve cannot be disassembled to replace the stem packing. Ned Kleinhenz '95 E300D x2 '85 300D '80 300TD
