Hi I've got a leak from my power steering pipe the metal 1 near radiator I've been quoted 700 for parts is there anyone who knows where to get a second hand one.

 

Replace it. Order the hose first. Make sure it's the same size and actually fits. Remove as much power steering fluid as possible from reservoir using a turkey baster or whatever you have on hand (obviously use dedicated tools if you have them) remove both sides of hose, replace and then add fluid back in. To route the hose easier you can tie the new to the old (end to end) making it easy Nox Vidmate VLC to pull through cramped spaces when replacing it.
