what are these 4 lines (W126)
Let me first say the the local MB dealership parts dept. did not know the answer to my question, and asked me to bring my car in.
Dumb question: I have a 1983 380 SEL (W126) and I have some fuel and rear brake lines I would like to have replaced. My question is: What is the "3rd" line?
metal fuel line #1 = supply line coming off the fuel filter
metal fuel line #2 = return line to the tank
metal line #3 goes to a plastic part the size of a golf ball attached with braided lines at each end of this part (which is falling apart)
metal brake line #4 is the rear brake line
these 4 lines run millimeters apart, for the length of the car.
