I have to replace my turbo oil feed line on my 97 A4, and was wondering what size were the female fittings on the ends of the turbo oil feed line. These are the fittings that screw on the oil filter adapter and turbo oil feed, since the stock oil line is expensive, I'm just going to get a steel braided oil line from ebay, but I need the sizes of the ends.
Thanks!!!

you can get a fitting for a -3 or -4 line from atp. But it would be cheaper to buy a used feed line from someone that went BT on here or on vortex/audizine
