There is a tiny vent hole already there (at least on mine).  The fluid will
come out of the vent hole.  We did it last week and didn't even have a good
pump.  We just squeezed a plastic bottle that had the fluid in it.

(my header is not removable).  So is there a cap or fitting or anything
on top of the master cylinders that needs to be loosened to vent the
cylinder as the additional fluid is pumped in, or is there already a
vent there?
