Review on BikeMaster 1L Pneumatic Brake Fluid Bleeder: Essential Motorcycle Tool Accessories - White/Black, One Size by Paul Lewis

Haven't used it yet but I'm sure it will work much better than a Mytivac hand pump as it handles a leaking drain plug better. Mine came without a muffler. It must be fully screwed into the device as it is part of the venturi, you will not get a vacuum if it is not there and a very slight vacuum if it is not fully seated. 84" hose from adapter to adapter. I measured the vacuum with a reliable but uncalibrated gauge. Air Pressure Vacuum 40psi 8" 60psi 14.5" 80psi 17.5" 100psi 19" At 19" it starts Firstly, these types of bottles can tear at the seams under stress, for this reason I will not work at more than 80psi.
