      Opti Spark Vacuum lines

      I am trying to figure out where the two lines go. One has two check valves and I have it plugged in to the manifold below the throttle body. The second was cut, so I am unsure where it goes, if it needs a check valve, or if it is a vacuum line or a drain. Any help?
