P0457 - fuel cap loose/off

So, here is the situation. I get this CEL every day in 6th gear at 70mph and about 2800rpm. I have tried to check and retighted the gas cap...no luck. I then did a search on this CEL and found a thread regarding the blue T connector just left of the alternator. Sure enough, the bottom vacuum line was just hanging there. What is concerning is that the line had a plastic connector in the other end that looked like it was sheared off I can't seem to figure out where this line would have gone to. There are no other vacuum lines available. I even tried to T it into another line just to see if it would solve the problem, but no luck. What am I missing?? Any suggestions?

Thanks, but I figured it out. There is a sensor just to the left of the alternator, attached to the intake maniford that has 2 nipples off of it...one on top of the other. The bottom one was completely sheared off.
