    So I have been looking through my recently purchased car, and I am noticing a lot of weird 'modifications' I don't trust or fully understand. I am having issues with vacuum lines and my MAP. I will attached some pictures from my phone shortly. Basically, the MAP has a vacuum line attached to something that I do not recognize what it is. Is this vacuum line location ok? If it isn't, I know where to tap the MAP into, but where do I replace the line to the part I am unfamiliar with? Also, I took a few pictures of lines deleted and wanted to confirm they are ok to be deleted. I attempted reading the 1g vacuum line diagram and didn't understand it. Any help would be appreciated, bought the car the way it is and trying to bring back some glory.

    The first image if they stayed in order is the map and it's line, second is where the line ties into, it is behind the intake manifold under the cables. The rest are lines I have questions about their functionality, including if one needs to tie into the BOV. Thank you again.
