The O ring on the valve which screws into the hydraulic pump has blown on my HDI
Managed to bodge it with PTFE tape temporarily.
Does anyone know the O ring dimensions please ? Will get one from the local belt and bearings place.
Hydraulic pump O ring size ?

I've got some at home for my XM. If it's the same ones I'm thinking of then the pumps look the same between them.
I'll measure them tonight if I get the chance.
Citroen sell these and my local dealer had them on the shelf. They were less then a quid each from memory.

When you say valve, do you mean the 17mm hex which the pipe comes out of?
If so, get two of the o-rings and replace the one under the similar blanking plate further around the pump.
You could also get the large o-ring that goes between the pump and the powersteering bell end and replace that.

Yes, that sounds like the one except it's a 19mm hex. The main pressure feed does take off from it.
There is a bit of a story behind the problem. The original O ring started to cause a slight leak and I replaced it with one from my assortment box, but I don't think the size was quite right hence the subsequent failure.

Get theco-rings from the dealer as they're so cheap

My local dealer would never have them in stock, they no longer even stock LHM !!!
There is a local belt and bearing place that sells this sort of stuff, from experience I know they will will be about £0.40 each !

It's on the hydraulic pump not the diesel pump, but it's ok, nitrile O rings will resist either.
