I have a Motive bleeder as shown above and it works perfect for a small shop. It's near as good as one of the expensive commercial models, but it gets the job done quite well.

If you are looking to use hose immersed in fluid, make sure nothing comes loose or the hose end gets above the level of the fluid. I don't like this method for flushing myself. When you pump and then release, you suck a little fluid back up the hose.

If I didn't have the bleeder, I would prefer the speed bleeders, or good old fashion two man bleeding over the immersed hose method. That's just been my experience.

Good luck,
