I have a quick question, how do you remove the hydraulic lines for the clutch from the master cylinder and the slave cylinder ??

there are no nut or clamps, it looks like the lines go straight into the cylinders. it looks like there is a set-screw or something near the hole for the lines. is that it.

 

I see in your sig both of your cars are automatic.. what are you working on? Internal or external slave cylinder?

 

There's a roll pin.... you drive it out, and the line has a fitting on the end of it with a little groove that the pin goes through to retain it.
