Looking for a fitting size

[Steve885]

I need the thread size of the stock water return line from the turbo to the pipe running across the block..I hope that s clear enough.. My car came with t4 setup some hack took the water line and crushed it flat so I'm looking for a barbed fitting to replace the crushed one..I'm reinstalling the 16g with some kit I got from the net

Why "hack" the original hack? These are cheap and easy to find: click

That will be an inverted flare, like a brake line. Just buy a water pipe and factory line, then cut and bubble flare the tube for the return.
