    Just read a thread on OCD and thought I should ask this question. I am being serious.

    Can you buy rubber tubing suitable for LHM coloured green?

    If so, likely only in silicone. I've seen red, blue and yellow, so green isn't a big stretch. You may have some luck with McMaster-Carr. You might also try some 'tuner' outfit- the colored tubing is (or was) popular with the Japanese performance-car crowd. You're thinking of return lines?

    15 seconds of Googling nets this:

    and this:

    You might want to PM Citroenfan (Steve), and check to see about compatibility.

    Hi,

    I did a google search and didn't find anything. All a matter of the words you use to search for.

    Your google links showing up but just taking me to google so I would really appreciate it if you could post them again please.

    I've used clear plastic tubing for return lines and also from the LHM tank to the HP pump inlet. Looks LHM green when the LHM is flowing (or a yellow green if the LHM is a bit old).

    Other than that, use fuel line black rubber.

    I thought you had to have special hose/tubing for the LHM. Resistant to mineral oil degradation.

    From your advice/comments I am assuming that silicon hose is ok.

    I was not all that serious about the hose/tubing but while I have the engine out I was going to replace the hoses so was jokingly thinking that a different coloured hose/tube for the LHM might make future work easier.

    Not sure Laurie, but others are using plastic hose.

    Silicon is more inert that most plastics.

    The same supplier sells vitron, butyl and edm rubber as well.

    So they are bound to have something suit, not necessarily in color 'tho.

    Do a test for yourself with silicon rubber and LHM !

    I'm pretty sure silicon is no good for mineral oils ( coolant is fine though ). Nitrile is what you use for LHM/mineral oils.

    Fluid and Rubber Compatibility

    For long term stability.

    LHM or other mineral oil based hydraulic fluids - Buna-N (Nitrile rubber)

    LHS or DOT 3/4 brake fluid - EPDM (ethylene propylene diene monomer)

    For use with both where some to moderate degregation of the rubber can be tolerated - static seals for example or where both fluid and environmental resistance is needed. Rear suspension boots for example. Neoprene (polychloroprene).

    Silicone tubing will not work with LHM or like fluids. It can also be compromised by some formulations of Dot 3/4 brake fluid - Wagner 21B comes to mind.

    Overflow and fuel lines are 6/6 Nylon tubing (more flexible than Nylon 12)

    When the factory switched fluids the LHM rubber lines (main ones) had a green stripe applied to the surface.
