I had a question with regard to the clear or somewhat opaque fuel lines that are connected from the injection pump to the main fuel filter . They are fastened by banjo fitting. The ones on my 240D and 300SDL are quite brown and you can't see through them any more. Is there a certain time that these lines must be replaced? I've looked through the maintenance manual and don't see any mention of it. Mine are not leaking but being that they are made of plastic I was wondering if they are to be replaced often. Mine appear to be original.
