This vacuum bleeder sure made life easy...
I just finished replacing all the steel brake lines on the CJ-5 and of course needed to bleed the brakes.
This thing made it a snap.......and it makes my wife happy that she no longer needs to push the brake pedal repeatedly...

I used 40-50 lbs of air pressure, and first sealed the threads on the wheel cylinder bleeders with a little Permatex thread sealant, as the vacuum can pull air through the threads.
Just one glitch easily remedied.. The bleeder comes with an I/M style air fitting, and it is locktighted into the bleeder....so I got a coupler and put a T style fitting in it and now have an adapter for my system.
