HI bork x 3

I looked through the 2011 Mercedes models and found a line tubing that is kind of firm and very shiny with a pattern on it on the outside and yet kind of soft onthe inside and I use it for both the w/s washer line as well as vacuum lines. So far, so good. I have replaced lots of stuff here and there in my 240 with more modern and "better" materials than was OEM. I know it is a form of sacrilidge (sp?) but I feel I am enhancing my car by doing so. I also removed and "erased" the flat-black vinyl on the tops of the doors outside the windows with a new type of vinyl used in the industry and now I don't have the spider-webbed effect on the original stuff. ( but I think I posted about this once before, so I am repeating myself here). Good luck.
