If so, at some point you have to take the top off and add fluid to the MC correct? And like mentioned above, is it messy when you take the top loose while there is still pressure on the system from the pumped in air?

With my homemade unit, I put brake fluid in the garden sprayer. As I release the bleeder screw, it pulls in fluid from the sprayer to replace what's coming out. The master cylinder level stays the same.
The garden sprayer has a simple "pull up to release pressure" valve on the jug so I can let the pressure off when done. There is no pressure when I take the M/C lid off and so far this system does not overfill the M/C.
A couple things to point out,
It doesn't take a ton of pressure to do the bleeding, nothing like actual brake line pressure.
I use simple air chucks and fittings so I can leave the lid on and quick disconnect from the front reservoir to move to the rear.
