I like my method of using a plastic tube to recirculate the fluid from the bleed screw back into the master cylinder. I use 1/4" clear vinyl tubing, with a short piece of 1/4" fuel line to connect it to the bleed screw. When flushing old fluid, I keep the MC topped off while pumping the pedal until all the dirty fluid is out of the tube. To bleed the system of all bubbles, wait until the fluid is clean, then stick the plastic tube into the MC and pump full strokes, not too fast, until you see no bubbles anywhere in the plastic tube. This system allows one person to bleed the brakes and to do it very thoroughly, pumping as long as necessary to get all bubbles out.
