replacing fuel filter on a 300E...
Hey everyone. I am having some trouble with my fuel filter on my 1992 300E. I can get the front connecting screw off easy enough, but I can't seem to budge loose the back nut fastner. I tried to use a cheater tube, but I still could'nt break it loose, and I don't want to break something else in the process. Is there a trick to loosening the fastening nut? Thanks.
