Looks cumbersome. I never bench-bleed on the bench. I install the MC on the car and use the pedal to bleed, w/ tubes looped from the ports back to the reservoir. Cheap plastic tubes often come w/ a rebuilt MC. Usually takes at least 50 pumps before you see no more bubbles. Some of my newer cars might be the "stepped bore" mentioned since look similar to the youtube.
