Brian,
Just signed up myself today, so you are more senior than me. I had the same problem 2 or 3 weeks ago. Went to a garage who made a temporary repair. Just order a new hose off of e-bay -(genuine Land Rover part - cost £26 including postage). I will fit this myself. You just need to unscrew the 2 large jubilee clips, pull off the old hose and replace with the new hose and then tighten up the jubliie clips. Unscrewing the top jubilee clip is easy, the bottom one is slightly more fiddly.
Hope this helps
