Thanks for your reply JFP. I used time instead of a gauge. If the system holds a low vacuum for a full 30 seconds my sense is any leak is less than a pinhole. I think I'll go check it for a full minute though. I did listen for a hiss as well and did not hear one. I bought a plastic vacuum pump similar to the one you show to bleed the clutch as it was marketed for use in brake jobs. It would have been a better tool if it was compatible with brake fluid.
