Hydraulic pump return pipe leak

Just browsing through the engine bay after my Xantia fell into a coma today and realised that I still have the temporary fix for the thick hydraulic pump return pipe to stop air being sucked in. Its on the bend right above the pump. I did look to see if I could get a new pipe from the stealers but they wanted £120 for the whole octopus

Im begining to get a little stressed as I want the Xantia to pass its MoT and a few bits have now started to stop working such as the engine

(see blog).

Does anyone have any ideas for fixes? It's only a small crack. My current fix is a tie wrap pulling the bend to a local bit of metal...I can't remember where the other end was attached....I might get a photo up in a minute, to explain it a bit better if I can find a decent torch

EDIT:
Heres the photo!
The red arrow is pointing to where the small crack is. Its on the bend of the corner.

Do you mean the suction pipe to the pump Kev?

The "normal" fix is to splice a new length of suitable pipe in with a straight connector. A piece of 15mm copper water pipe may bo as the connector but do make sure the pipe is sound as if it's still a bit "iffy" where the joint is made, it won't last... My old Activa had such a joint in it and that was (and presumably still is) fine.

A picture will hep immesurably Kev

Picture up.

The car looks dirtier than it actually is

I thought that it might be the suction it wouldn't make sense being a return to resivour as the PAS was terribla

, is that still called the 'return' for some reason though?
I must have understood the citroen parts dealer incorrectly...

Yep, that's the suction pipe Kev and a common enough place for them to go. Apparantly the flow of LHM is enough to abrade the rubber anwat and wear a hole on corners. All the "rubbish" that accumulates on the LHM filters originate from tiny particles of these pipes eroded away by the LHM flow

Go to a scrappy, cut out a length of good pipe with a similar bend and splice it in. There's no pressure there, just suction like on a diesel fuel line.

..or replace the bend with a copper elbow and a couple of short pipes.

I have a couple of those pipes that end - they have worn firther down were it passes over the regulator!

I could send you a top half if you fancy splicing it in with a join as mentioned!

I have a length of green garden hose on Cassy as I accidently sliced through the pipe with my sphere tool

It's working a treat, but to prevent kinks I take it up to the top of the engine, over the induction pipes and straight onto the resevoir.
