    I just got a 72 Dart Swinger and was looking to hook vacuum lines so heater would swap positions. Have the 2 lines in engine compartment and wondered if anyone might know which to hook to intake? Thanks....

    I believe that they both go to the intake...

        I've read that one goes to manifold vacuum and the other to a heater hose control valve.

        That's actually the reason I dropped into this subforum, I wanted to know if I can just run a vacuum line to one of the lines and plug the other to determine heater pod function without damaging the pods in the process.

          That could be also...

          See what the service manual says...

            I see they have stripes on them. If one is red, that is usually manifold vacuum.

              One is vacuum in to run your control pod, the other is vacuum out to run the heater water valve. You won't hurt anything by testing
