    88 MGM Vacuum line routing

    Hi all,

    I'm an idiot. Took off intake plenum to replace valve cover gaskets. Now can't remember what hoses go where. There is a large pipe pointing to the front of car under the plenum. What connects there?

    The problem was compounded by some hoses disintegrating.

    There is a sensor that bolts onto passenger side top of firewall. It has a nipple on it and an electrical plug. What hose plugs on the nipple? This the MAP right?

    Sorry guys! I just jumped in on the job.

    The tree facing the back should have one fat and 2 skinny lines. Fat goes to the vacuum tree on the firewall. One skinny to the emissions stuff on the fender, the other goes to the fuel pressure regulator.

    The single med size fitting facing the rear in the center goes to the MAP sensor. Thats the black thing on the firewall with the plug.

    The one on the front center goes to the evap solenoid that hangs between the fender and the engine

    The other one on the front center loops to the T on the rear corner of the manifold, other side of the T goes to the PCV valve

        The evap solenoid that hangs between the fender and the engine is the same as E4ZF-9C915-AA Vapor Canister Purge Valve? The must be true because she's running right now.
