On BMW's you just have to keep cycling/operating, rechecking fluid level. The pump will quiet down when finished.
no you do not yo may have to bleed out all the air
There is no need to bleed air from a fuel pump.
hydraulic pump
Bleed the air out while running your pump. Either through a specific bleed valve or by loosing the discharge pipe at the pump until only fluid runs out of it.
It probably has a hydraulic clutch so you will have to bleed the air out of it.
Hyd clutch has no adjustment, pump clutch pedal hold down bleed off hydraulic slave cylinder on driver side of trans. If won't bleed replace if bleeds off no air in line & still not better ck bushings on clutch pedal under dash. Hope this helps
check out the "where is the convertible top motor on a 97 sebring convertible"most the time that's the hardest part other than containing the transmission fluid that will leak from the pump when you remove the lines hooked up to it, the other tricky part is purging the air from the pump and the lines once you have replaced it. you have to have the correct size line wrench to remove the hydraulic lines from the pump, and you have to have a socket set and some other basic tools to remove the back seat to get to the pump.
Pneumatic. Pneu = Air. Hydra = liquid
normally you keep turning the steering to full lock both sides and the pump should bleed itself.

Air Conditioning Vacuum Pump.
bleed the air tank by pushing down on the air stem, remove the pressure from the water tank,add correct amount of air to bladder, then start pump.
