    Default Fixing hydraulic line DS23

    Hi everyone and Happy New Year.

    I have finally foundthe source of a major hydraulic leak. It was from the vertical rubber line down to where it meets the metal Tee piece on the left hand side of the engine against the wing.

    My question is: as a temporary repair can I substitute fuel injection hose for a high pressure hydraulic hose?

    You mean a metal line ?? NO !!!!! fuel line probably has a burst pressure of 80psi, the hydraulic system is a couple of thousand psi

    The only hose I can think of that fits your description runs from the top of the pressure regulator to a Tee junction - and yes it is rubber - If so, I would use power steering hose with as close to the same internal diameter as you can source until you can get the correct hose.

    Cheers

    Here is a piccie of where the leak is (arrow) that is on the left hand side of car at the bottom.
    Where can I get a similar rubber line do you think.

    I reckon it should be my last hassle and after that I should be back on the road.

    The rack return perhaps? There is a rubber return there in 5x11 rubber and it runs straight down with a large kink. Anything OK for low pressure mineral oil will do.

    While you are in there, consider replacing the regulator return and some of the other rubber lines. The short one at the crossmember looks original = brittle and waiting to turn your car into the Exxon Valdez.

    I missed re-read the rubber bit... like they say, any mineral oil line will probably do (yeah fuel line should be ok too).
