regarding brake lines automotive. My understanding of hydraulics and how brakes work is that when you release the pedal it stops applying pressure to the brakes thru the hydraulic line, but it does NOT suck fluid back.
so as I see it closing the bleeder valve between each pedal push is not...
I have an automotive application. OEM "rubber" hose on this engine often fail. After several years the manufacturer replaced it with solid line. Earlier year owners often swap out the rubber for the later year solid. This is too involved for me right now, so i was just going to get the best high...

then lift...
