I was thinking that maybe I could fabricate a new line from some stock brake line. As for protecting the line from further chaffing, I would use a piece of rubber hose, slit it length-wise and wrap it around the line. The clamp is held in place by one of the oil pan bolts. Today I am going to take it over to my indy. and see what he says. I have never done any brazing, but LONG ago, in highschool I did some soldering on copper piping. I have a pipe cutter, so all I would need is a basic pipe bender and a tool to flare the ends.
