I used the vacum brake bleeder again today. Was doing complete fluid change and got sick of pumping. So put the T piece in near the squeezer, connected another long hose and hooked it up to the inlet manifold. Started the engine and bingo, just made the task so much easier and quicker!
Obviously need to watch so you don't make the little catch container too full and suck fluid into the intake but it's easy to keep an eye on. A more fool proof solution would be to insert another catch container in line to the intake.
