Thanks for your help and replies, very much appreciated, it gave me the confidence to have a crack at it myself, I did ring Pirtek and the lad at the local depot was very helpful, so I cut the pipe .......... :shock: and replaced the leaking section with a piece of high pressure hose and 2 hose clamps, all seems fine now, have even cleaned the drive!
Photo shows the offending leaky piece of pipe.
Total cost, about 4 quid!
:D
