Does anyone know thwe correct way to fit the little rubber seal on to the largest mwetal pipe on the Hydraulic pump........
It did not have one on andf it didnt leak now I have a new pump it leaks I tried the seal it still leaks HELP

- this is the preferred method to avoid the sharp pipe end cutting into the seal.
You might have another problem :
- under the larger insert nut - there is (/should be) an O-ring - which tightens this insert nut against leaks. Check this.

I think that you probably need the help of a manual. Any Haynes that deals with Hydro Citroens will give the necessary precautions and procedures. There are usually copies at the local council recycling centre for about £1. Trying to work on these without a manual is asking for trouble because there is a certain amount you have to know before fixing the hydraulic bits. It is well worth the effort, though. once they are working, they tend to stay that way and there are few cars more comfortable.

Hi there.
I did the O-ring on the large insert nut a short while ago to cure a leak from around the nut, the smaller pipe that goes into the large nut insert wasn't leaking on mine.
If you remove the large nut, I recommend disconnecting the LHM inlet pipe that runs from the reservoir to the pump, syphon action seems to drain the entire reservoir otherwise, when you remove the large nut.
Remove the small pipe, get it out of the way carefully and then undo the large nut, be prepared for LHM leakage. When you actually remove the large nut, do so carefully and recover the spring that's underneath it, if it pops up out of the little metal piston type thing it sits in deeper in the hole that the nut screws into. Both of these parts (spring + piston) can be removed and may come out of their own accord with the hydraulic fluid that comes out. The large nut is in fact quite deep and barrel-shaped. The bottom of it presses onto the spring, the other end of the spring is located in the hollow of a metal cylinder (piston). The piston may remain deep inside the pump in which case it's safe enough, but I'd watch and guard the spring carefully, as I was told that the spring cannot be purchased as a replacement part!
While purchasing the O-ring for the large nut from the Citroen garage, I was chatting to the fellow behind the counter about the job in hand. As well as the warning about the spring and the consequences of losing it, he also spoke of the little pipe that screws into the large nut insert. This pipe does not have a seal (I wanted to know if I should purchase a new one for it, since I'd have to remove it to remove to large nut) but instead has a flared end that makes metal to metal contact inside the large nut insert.
When I did the job, I found out that he was correct, no washer or seal at all, just a flared pipe end that pressed against the smooth metal curved bottom of the big nut insert (this may be why you discovered no seal when taking it apart before). I did this up fairly tightly and had no leaks at all from it.
Perhaps the flared end is scored or otherwise damaged? Is the smooth bottom of the big nut where the smaller pipe goes into damaged at all or scored?
Hope this helps.
