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.

I don't care for vacuum brake bleeding tools at all, I prefer the pressure style like the Motive system because it pushes clean fluid downward and through the system without any chance of pulling air in, which a vacuum system can quickly do.
