I'm pressurizing the master cylinder with a setup I made.
I taped a hole in the top of the old master cylinder cap and put a barbed fitting in it.
I run a hose from there to a reservoir, an old sprayer tank.
Then I have a air line fitting tapped in to the top of the reservoir.
I use the regulated on my compressor to keep it at 20 psi.
It seems to work pretty well. I can put up a picture tonight.
