Rear Brake Proportioning Valve

[volkdent]

Speaking from recent experience, if you just cut the stock VW line, you can re-flare it for the double-flare 1/8th". I can't guarantee this, but I think if you get a Wilwood brake proportioning valve and a couple of nipples, you can just cut out the stock line where you want the valve, double-flare the ends, and bolt that up to the valve. Then you'll have hybrid lines, half bubble metric, half 1/8th NPT. I used the stock VW lines to tie into the steel braided cables that are meant for VW Jetta, and the other end I did to attach to a standard T. The only think that might be a problem for you is that I would want my valve within arms reach, and unless you can pull any excess, the valve would then be low where the stock line runs.
