Last night I was in the process of changing the fuel filter on my '92 190E and as I was unthreading the outgoing line from the filter the metal section of the fuel line right by the filter twisted and broke. It was badly rusted and the nut that is supposed to spin freely was seized to the line.

I have an appointment at the MB dealer on Monday. What items are they going to have to replace in order to fix this? Are they going to have to replace the entire fuel line? The service advisor I spoke to said that it will be a major repair. He emphasized the word major which made me cringe. Any thoughts? Thanks!
