I have a 1978 300D non turbo. I noticed the other day that my fuel injector return lines are wet (the braided lines) are wet and one of my injectors has some fuel pooling around it.

I want to replace the lines before I dive into the injectors or whatever, so would I be correct in the following assumptions?

(1) I don't have a Mercedes dealer in the area, but there is a VW dealer. The braided fuel lines they carry for their older diesel rabbits is the same as what I need?

(2) The lines just carefully pull off (they may fall apart) without clamps or washers or whatnot

(3) Replacement lines can just be carefully pushed back on.

(4) The last line needs to have some sort of plug in it. I can re use the metal plug in the existing line.

Thanks in advance, and any advice/feedback would be appreciated.
