I have been playing with a bleeding tank. I did my entire system which was new (MGB). Worked well. Pump is basically an airbrush pump I believe with the in/out ports swapped. I just hook it to a tank and draw the fluid into the tank.
This is old photo. After doing it this way a while I ended up taping a second hole into the tank to atatch the vacume so the pump can run while I bleed:
I tried a presurization system and blew out the fluid so fast I had to prime the MC again.
