nut removal
as posted earlier, the pipe i want to release is the metal high pressure pipe on the hydraulic pump.
The pump itself has come away as the bolts have sheard off!
This is making it incredibly difficult to undo the nut.
Im also hindered by the lack of space in the engine bay, whihc means i cant get the appropriate leverage?
I did notice the same on the scrap car when i removed it, so i simply cut through the metal pipe. Then when i went to undo the nut it was very easy? is this due to the fact that I had relieved some pressure?
seems a simple explanation. If so, how can i unod the nut without damaging the pipe?

The obvious question, have you made sure that your accumulator sphere is depressurised (12 mm nut on the pressure regulator)?
If you have, the only thing I could suggest is plus gas and a little time or trying to get at it from a different angle with your spanner. Maybe a length of pipe on the spanner might help if you can get it in.

The obvious thing would be to jack the car up on its suspension (and support it) so you could get at the pump from underneath (assuming you didn't have had aircon). It would be obvious, if the hydraulic pump was working...
Do you have access to any ramps? Is there a convenient curb you could put a wheel or two on to give you some more clearance underneath the car?

not likely mate! It took me ages to find a scrap car with this pipe/pump on it! like gold dust round here! only thing for it is to get it off the correct way im afraid.
the only problem working under the car is the fact that the more i try to turn the nut, the more the pump turns (and therefore the pipe bends - NOT GOOD)

If you have turned the pump through 180 degrees, the pipe must be rotating inside the collar or it would long ago have sheared off. Can you not get to the other end of the pipe on the regulator and remove the pump and pipe together so you can get proper access to get the nut undone? The pipe is unlikely to be THAT expensive, and if you can find someone near you that can make copper pipes up a replacement it will be pretty cheap (it not Plaeides do mail order, and may well have that pipe on the shelf, but if not can make it up for you if you tell them how long it is). You might slip with a spanner or hammer down there and put it through the rad, which WILL cost way more than a new pipe....!
