I've used a Mity Vac system in the past,matter of fact the case is gathering dust in my garage ever since i purchased a Motive Power bleeder from our host ...
I will never go back to any other system as i've done my Porsche a few times along with
my F150 and my son's Civic by using the universal adapter !
Bleeding brakes ... down to a simple one man operation
Cheers !
