I have learned a couple tricks that work well. I take a pop bottle and drill about an eighth inch hole in top, big enough for an eighth inch primer line. Stuff the end of a foot long piece in there. The other end goes to the bleeder. Sometimes a zip tie works to hold it. Now make sure the line stays full of fluid and crack er open. Let it run in there awhile. Close and bleed. Repeat if needed. You can also drill two holes and put another line in there. If the bottle is nice and stiff you can suck on the line and not get fluid in your mouth. Hey it works.
