The other hard line attached to the switchover valve (with a small rubber connector) is the broken one.

If you trace the broken line to the PS side of the engine, it should be attached to the rear of the intake manifold.

Your broken line is now venting the boost to the atmosphere preventing the ALDA from permitting the full range of fuel delivery by the IP.
Very helpful! I will lay eyes on it again this evening when I return home. Thank you thank you!

Something I'm a little worried about.. If the line broke off flush with the banjo bolt, I wouldn't be able to slip the vacuum line over a male end. Would I need t remove the banjo bolt and insert a fresh hard (plastic) line?
