    Just replaced spark plugs and ended up with a left over vacuum line, it's the one next to the red line where the mbc is fitted, the pipe which connects to throttle body, thanks in advance!

    Tiny little nipple on the plenum near the throttle body on the inside maybe?
    It's quite important since it controls fuel pressure.

    Nah the fuel pressure solenoid has a hose fed from the fpr then is feeding the nipple under the throttle body, so that's all functioning fine, however I can find where the line on the intake is meant to be feeding? Vacuum control solenoid maybe? Or power steering valve? I'm not too sure

    Here's a couple of vacuum line diagrams that may help.

    Thanks mate it is for the power steering, also what's the importance for the one way valve in the line feeding the charcoal canister? Mine broke haha
