Hi I have a 91 560 sel 145k miles..with what appears to be fuel problems..when I get it started it runs rough.. and when I give it gas it dies. I think my fuel lines are rusted.. I take off the lines going to injectors and there is so little gas coming out I cat tell what color it is..I have not changed the fuel filter.. I know there is a filter in the distributor but I am not quite sure where I would like to change that as well.. any idea where the filter for the ditributor is.. btw the filling stations in out town are nortorious for having water in the fuel.. Im thinking of putting another filter before the fuel distributor if this proves to be the culprit..I think we have the same problem..good luck
