I've bled it 6 ways from Sunday....at the joint where the flex hose connects (just under the passenger fender well), to the steel tubing and also at the slave cylinder. I've taken the tubing loose at the master cylinder and when the clutch is pumped, I get strong hydraulic pressure there. I've tried the usual of pushing in on the clutch while holding the hydraulic line shut, then opening the line to let pressure and air out. But I never can get any pressure build in the tubing. I'm guessing there is a tiny hole somewhere that is fooling me into thinking the tubing is intact but it is not. Normally if the hole was there, I'd not be able to siphon fluid from the master end to the slave end.
