    Where does this vacuum line go? H22a

    Hi guys,
    here is a picture of a solenoid mounted inbetween the rocker cover and inlet manifold of my gen4 vtir.
    A vacuum line comes out of the inlet manifold, goes into the solenoid and out to the FPR.
    Although there is one port left open in my case.
    Where does the vacuum line come from for this port of the solenoid?

    Thanks!

    If that is the FPR (fuel Pressure Regulator) It should have a vacuum hose going back to the intake plenum.

    Mine's got a thing like that, but it's not bolted onto anything like yours is - ogften thought about finding out where it should bolt on, but always forgot. So thanks for that pic!

    For info, mine has a little round black cap thing on that tube, about 2cm diameter and 1cm high.

    Yeah I had a look at my mates VTiR, and it has a vacuum plug on it. Just go pull a vacuum plug from a car at the wreckers or something and put it on.

    Thank you Angus!! Im assuming from what yoú've written, the solenoid is supposed to have a vacuum cap over it, ... a blocker.
    Which would make complete sense, since i cant find another open port for a vacuum line to go to.

    Thanks for your help

    No drama, mate. Seems to be confirmed by what the other guys said, too. Thanks for your help, as well!

    That looks like an electric switch that turns off or on some type of vacuum operated device . One hose supplies vacuum to the switch and the other hose should run to some vacuum operated device . Something that the ECU needs to turn on and of is not working . I would keep looking .

    Note : Did someone remove the sophisticated , stock , 2 speed intake pipping with its vacuum operated actuator and replace it with a low tech , aftermarket intake . That might explain why you can't find the vacuum device that you are trying to connect to .
