My new MC came with a plastic plug that I screwed into the outlet port. I supported the MC in a vice. Filled the MC with fluid and slowly pumped the rod while looking inside the reservoir looking for the air bubbles to stop. Takes 10 or more pumps to eliminate the air.

I’ve also seen a kit that contains a nipple and a tube (or two for dual MC) that screws into the outlet, then you place the tube into the reservoir filled with fluid and pump until there is no more air bubbles in the tube.

It’s important to keep the MC full while you bleeding it.
