I can normally get them out without much of a problem. Put the vehicle up on a hoist or jack stands. There is enough room to get a wrench in there, if I remember right it's 7/8? I usually just use jacks stands and lay on my back so I can get my arms far enough up in there to get to it. Shouldn't have to remove anything else. When reconnecting the vacuum lines, there is a pin on one side that goes into a hole on the connector, all three lines come off and go on as one unit.
