Power steering fluid leak

Evening All, Disco 2 2001 TD5
I appear to have a power steering fluid leak and I think it's coming from the pipe directly under the radiator/intercooler. By peering with a torch between the bodywork and intercooler I can just see that slightly left of centre the metal pipe is wet and fluid is appearing dripping on to the road in the same place although the whole cross member is covered! the reservoir has dropped by about half an inch. This same pipe goes off to the steering box but appears dry on the upright. The feed and return to the reservoir are dry and the pump appears ok as well.
Question,
I take it I have to buy a full set of power steering pipes ? Where? and is it a pig of a job to do?

Thanks all.

you can get pipes seperately high pressure pipe (pump to box) qep000082

Try DLS landrover spares I got a set from them & did mine a couple of months back. Hardest part is time taken to take everything out to get to them, could be possible to leave everything in but need to be careful.
