Disco 2 anyone no the part number???

Hi all does anyone no the part number for the o ring that goes on the pipe that connects to the power steering pump, just fitted a new pump and no o ring came with it , put it all back together without thinking about the o ring ,no leaks but when at idle the steering is very heavy ,once some revs are on its spot on but not till, im thinking maybe with out the o ring maybe air is getting in????

cheers

IMO you better bleed the system well cos it's no way for air to get into a presurised system while running ... it will leak oil out not suck air in...about part numbers find them yourself http://www.allbrit.de/UNI.cfm?PAGE=818057&SPRACHE=EN , for any other part click "back to navigation" on top of page and select what you want
