Front brake hardline size help

[garytightpants]

I am installing HP2's on my a4 and I discovered that the hardline on the caliper itself is folded over and pinched on one. I was wondering if anybody knows what size the stock tubing and the fittings are so that I can make a new piece. I have tried searching but found very little useful info.
This is a pic of the line I am referring to
