    Found a vacuum line that did not have anything connected to it. It is a 2" line on the driver's side back next the fire wall.

    Help...1995 Chevy Blazer Vacuum Routing Diagram needed.
    Only sticker under hood for vacuum lines is emission hose routing.
    I bought a complete Factory Service Manual & it DOES NOT show the routing for most of the vacuum hoses. Also have a Haynes which is not complete. Need diagram for ALL vacuum lines. AC/Heat, Brakes (anti-lock etc), Transmission etc.

    Where do you get a vacuum diagram. I've got the same 'unknown' loose hose on the drivers side too. Can find an unused port to connect it to.

    i have a 5/32 vacuum hose on the drivers side close to the firewall. it's at a T connector. the hose on the vertical part of the T is not plugged into anything and i can't feel around where it plugs in at. Its right in front of the cruise control box against the firewall. i've felt around under the cruise control box and felt no ports, its kinda tight under there also though. one of the hoses that go to the T connector is coming from the other end of the pcv valve. dont know if that info. helps you any but thats the best i can describe it, lol. preciate it
