    Does this show the vacuum line connected to it with it under the ICM?



    Does this then show the vacuum line attached at the other end emerging from under the ICM?



    I think this is the vacuum end of the pipe where it connects to the TB.



    It absolutely pouring outside or I would go take a look. It appears the '92 is two metal pipes and vacuum lines to do the job.

    I would suggest a long piece of vacuum hose to accomplish this (up and over the ICM) to accomplish this temporarily, unless you want to bend a new piece of pipe. I will be heading for a parts run when the rain stops.

    Its in the 2nd picture, with the rubber on the end, where the Throttle body and black bracket would be.

    Just for clarity, can you verify I circled (in red) what you need?

    Exactly why I wanted to be certain.
    That pipe snakes downward to the transmission vacuum modulator (4 speed only) on our '92.



    The vacuum port on the (now unavailable) vacuum block had a cap on it on 3 speed cars.

    Jerry sorry my mistake, no on mine there's a rubber house from evap canister, then the neutral pipe is fastened to the icm mount then snakes by the fuel rail to the Throttle body/Intake.

    Its the hose that runs from the top port of the vapor canistor to the small nipple on throttle body.

    I had to look again to make sure it was as I thought. I knew it could be confusing. I should be able to find you another one soon, if you would like.

    Yes that's it, strange mine had a mounting tab on it for the stud on the ICM mount. If you could find one that would be cool, or I was hoping vacuum hose would get me by for a while.
