Im attempting to figure out what size hose/tubing I need for my 85 300d turbo. After reading an hours worth of different answers around the net, my brain hurts. I know know less than when I started.
Whats the id on the return and the in-line?
can I use cheapy tube or does it need a heat tolerance..

thanks....

(was pretty sure i had it figured)
