Nix on Pieces de Rechange (PSA heritage).
Not suggesting you do this DIY repair, but it could help get those two pipes made up.
The ends look like standard hydraulic coupling. http://xantia007.free.fr/11_verin_SC-CA ... _tuto.php?
Skull can i ask a favour which may seem really strange
If you do get the new part can you send me the old one, happy to pay postage.
I have another silly idea but need the pipe complete with fixings to follow it through lol
