    Vacuum diagram?

    Hey, guys.
    Tried searching but couldn't find.
    Looking for a vacuum diagram for all the vacuum hoses on the engine. Bought a new girl and some of them have either been left off or blown off or whatever. But I want to pull them all off, replace them and give the engine a good clean. Admin still seems busy as I still haven't been changed to Full member again, so I can't look there. Any help much appreciated.
    :-)

    Thanks, Nick but I can't tell either as I haven't been changed to a full member and don't have access. Are you able to post a picture of it?

    Cheers guys. And ASA, I should've thought of that earlier. Much appreciated.

    What size are all the vacuum/ boost hoses? I was thinking of swapping most of the old rubber ones for silicone but thought I should check! (Searched but couldnt find a concrete answer, sorry for dead thread resurrection)

    4 to 6mm ID depends on location

    Now: Lancer Evolution 8 FQ-300

    Hmm ok, was hoping they were all one or the other But I'm particularly looking at the lines running off the back of the plenum to the boost controller, boost gauge and BOV.

    More details then (as I remember them lines ):
    - 4mm ID fuel pressure regulator, bulkhead solenoids (off throttle body lines)
    - 5mm ID - boost solenoid, wastegate lines
    - 6mm vacuum off back of intake plenum IIRC, but not sure
