Hi folks,
Does anyone know if lhm affects copper tubing as I'm seriously thinking of replacing my car's hose with a combination of hydraulic hose and copper fittings where bends are concerned.
My existing hose is weeping at the pump end and has been cut once/twice before.
Cheers Stevie

not sure about the copper pipe, how would it react with the LHM, but rubber for the bendy bits won't work at all because the natural direction change in the bends will eat the rubber more because of the flow on the corner compared to the straight.
my dream is to still get see through hydraulic pipes, suitable for lhm.

Ahh - but we dont have THAT much flow It certainly is no problem in the genuine hose sharp bends.deian wrote:not sure about the copper pipe, how would it react with the LHM, but rubber for the bendy bits won't work at all because the natural direction change in the bends will eat the rubber more because of the flow on the corner compared to the straight.

In fact you could make it up to 15mm copper then reduce to 10mm copper using standard plumbing bits. I have repaired my BX pump to reservoir line using copper, its been there for years

Hi Guys,
I found the same thing with my CX. There is fine cracks in the hose at the bends causing the pump to lose prime (randomly).
I went to the local hydraulics place, grabbed a couple of metres of the right sized hose (just whipped the hose off reseviour end and measure it's internal diametre .... Once home with the new shiny hose ... I found the other end a different internal diametre (much swearing at Citroen and the stupid cr@p they do, no doubt to ensure you buy original parts).
As a temporary fix I taped the existing hose up along it's length until I could make up a wider section of hose for the pump end and a joiner .... That was about 2years ago and counting I'll get to it oneday

Thats interesting... when you say lose prime do you mean it was completely losing its prime and was unable to pump until you manually primed it ? Or do you mean it was just sucking in huge gobs of air until it primed itself ?
I'm still monitoring a clear section of hose I have in the return line back to the tank, and first thing in the morning if I open the bleed screw before starting the engine, then start the car I get about 3 seconds of vigorous bubbling and frothing through that hose before it goes (relatively) clear again.
I'm guessing that when the car is left to stand overnight that even a tiny air leak in the hose at the tank end will allow the column of oil at the junction of the tank and hose to sink back down inside the tank and draw in several inches worth of air ? It certainly seems that way...
I did the opposite, I measured the pump end, got that size, and found the tank was biggerI went to the local hydraulics place, grabbed a couple of metres of the right sized hose (just whipped the hose off reseviour end and measure it's internal diametre .... Once home with the new shiny hose ... I found the other end a different internal diametre (much swearing at Citroen and the stupid cr@p they do, no doubt to ensure you buy original parts).
For those wondering, on a Xantia the pump end tube is 10mm, and the tank end is 13mm. To get a snug fit you need hoses with a hole that is slightly smaller, I ended up using 3/8" (9.5mm) for the pump end and 1/2" (12.7mm) for the tank end and both are standard sizes and a good snug fit that stops rotating with a moderate amount of pressure from a jubilee clip.
I plan to take pictures of the fittings and pipes that I use so I can document what I'm doing which will hopefully help save someone paying for the over the top Citroen pipe....
Regards,
Simon

Hi Simon,
I have these visions of a pig flying happily over a frozen hell before I'd pay those $$$ for a small length of rubber hose. There is most certainly nothing special about mineral oil hose that can handle a little suction. Infact is readily availabe quite cheaply by the metre.
Yeah what usually happens is the car will take forever to rise, what your infact doing is waiting for the pump to self prime. Once it does it then starts to pressurise and lift in the normal way.
CX's appear to be known for this more than Xantias though (my old ID19 tended to do it as well until I fitted hose clamps).
Yep, what is happening is the pump is developing air pockets in the suction hose when the car is left for a length of time.
