Hi I changed my master clutch cylinder and tryed to bleed from the slave. First as my partner pumped I was getting squirting and air then a solid flow of fluid so I closed the bleeder but we are not getting any pressure. I have a partner but its first time for both of us and I went back inside and found this o ring in a bag that came with new master. Do I need it and I'm guessing it goes where the line from the slave connects to the master? Any help much appreciated and I can answer any questions that will lead to helping me out thanks!
