Jeeze so yeah I broke a vacuum line to pieces when I put the rockers in and I have no Idea what it connected to. It'* the line that is connected to that "T" coupler and goes back behind the motor along the rear fuel rail. I have looks for like 20 minutes and I can't find what it was attached to.

I also found a module on the opposite side of the engine that seems to be missing a vacuum line but when I connected the broken line to the module with a hose the boost gauge still did not work so they must connect to each other.

Please can someone post picture of an l67 up close so I can figure out what the deal is with my vacuum lines?

the second pic is a FILTER, and nothing get connected to it


can you get some rubber vaccume hose and connect the hard line to where its supposed to go??

The other line in the back connects to the MAP sensor. It'* on the bottom of it, and can be a pain to get to. It'* easier if you remove the MAP sensot, or if you can find the other end of that hard line, put a rubber coupler between them.

yea thats what I was planning to do, whats the MAP sensor? THanks

Manifold Absolute Pressure. Your boost gauge runs off from it, so that'* why you're not getting a boost reading.

oh, which little module is it? the round one or the rectangular one below it

The rectangular one below it. The round one is for the evap. system.

hey man thanks I found it and fixed the vacuum tube but I have bad news. The vacuum gauge still doesn't work and it still nearly stalls once in a while while Idling. I don't know if I connected something back wrong or if there'* another leak somewhere... I'm scratching my head right now.

Double check all of your vacuum fittings, and pay special attention to the T under the snout of the supercharger. Those are known to dry out and crack.

Check the diagram in here to see the routing of vac lines. Although this is for an earlier year, the vac lines should be very similar, since it is for an L67. There are two map sensors that are connected to the t from under the SC snout.
