Sorry I took so long, my digital camera is broken and i cant find anyone who has one, but i did find out what that unit is, its the warm up regulator. Still no luck finding the missing vacuum line. There are a couple of vacuum line attachments on this unit, but only one on the top next to the electrical connection. The one on the top is the one thats missing a vacuum line. If you know where the vacuum line for this is supposed to come from i would really appreciate it!
Again, thanks for all your help Mike!
