I was replacing the battery on my 1998 Lumina with a 3.1L when I noticed a vacuum line hanging down behind the battery. It has a 90 degree elbow at the end but has nothing within reach to plug it in to. The line itself is broken and shows to be a two layer line. The line is attached with a screwed-in clip on the wheel well and has other vacuum connections prior to passing the battery. Does anyone know what this is and where its supposed to go to? Should I just plug it so the rest of the connections get full vacuum?

are you sure its vacuum and not the hose for the washer fluid tank? if it is for sure a vacuum line there may be a vacuum canister (looks like a round ball) under the battery tray. i cant say i can remember off hand, its been so long since i looked at one of those cars.

I know I'm replying to an old post.
That line is for vacuum. One end is connected to a tee and a one-way valve. The other end passes behind the battery and down to a vacuum reservoir canister. The canister is probably located in front of the wheel well. The canister looks like a plastic cannon ball.
Just a general diagram. The line in question is denoted by the blue arrow. Disregard the stuff in red.
