this one is a git..

gems powersteering pump.classic box..american hydroboost, oil cooler

it wont except anymore fluid in resovoir, jet it obviously empty as steering really heavy and whines the pump when on any load..as does the hydroboost when apply brakes...when cut engine fluid pours outa top of resovoir..AIRATED

today raised resovoir so above highest pipe..no change..

plumbed up as so..resovoir feeds pump.
pump feeds hydroboost
high pressure from hydroost feeds steering box.
hydroboost has low pressure return to T as does power steering box.
from T low pressure return goes though oil cooler returns then to resovoir..

I KNOW this works..all except cooler as this not tried before as use same on sally, sally even has two pumps, one electric as a backup...

this is baffling me unless its just not bleed yet, but think it is...

thoughts please.

update..needed a feck load more bleeding..took an hour or so!!
