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?
