I also noticed that when I have the master cylinder opened when I did the one time I had the line pinched the fluid shot back in a stream. I just tried so many things to try and get this primed I even have clear hose I can attach to the bleeder and used suction to suck out from the slave to see if i can draw all the air out which i do and i can pump the clutch and then hold it and closer the bleeder and i get nothing 0 clutch. And I am at a loss because I tried so many things and I am about to order all new postion in the master and replace all the insides of the master cylinder.
