    Catch Can hose length

    Here is a random one.

    I am running a legit PVC catch can on my turbo setup. I will be putting it in the inner fender.

    Im running the following lines:
    - a line from the TB to the PVC which is mounted on the can
    - a line from the valve cover to the can
    - a line from the other valve cover to before the turbo.

    Now my question pertains to the length of hose I will need to run (3/8th). Does anyone think I will encounted problems if I have to run like 6' of hose to the can? I figured it I kept it all level I shouldnt have a problem. My concern is going to be the strength of the vacuum on something that long.

    Any insight would be appreciated.

    depends how much maximum vacuum there is. The rubber hose will flex / collapse a little bit, especially if its hot and soft. Maybe run a more solid line part of the way? Pretty hard for a hose that size to fully collapse tho, which is the ultimate worry.

    Just the reverse of a pressurized line - I assume you're using fuel line which is usually good to 50 psi (?) or better.

    I would suggest hose that is oil resistant, yes like hydraulic hose or similar.

    Bought some hydraulic stuff...then returned it. It was a little too heavy duty.

    I did get the can mounted and installed a spigot on the air filter. And before anyone asks...NO that is not a simple breather setup. This is actually a factory style setup.
