Yep, that is the correct line if you have an internal slave cylinder on the clutch.
The 90 degree fitting goes on the master and the straight fitting goes to the hard line sticking out of the bell housing. gravity bleed it as much as you can before hooking up the line. get most of the air out, hook it up and finish bleeding the remainder of the air with the bleeder(other line sticking out of bell housing). Its going to take a few tries to get all of the air out.
