Ok I just replaced a dry rotted vacuum line that goes from under the battery to the transfer case. Problem is I think I pulled one of the other lines loose from somewhere. Ok so one goes up under the battery. Another goes up to the vacuum tank I think. The last one goes to a y connector another line from the y connector attaches above the tansfer case and another (bigger) line goes from the y over the transmission pan and is hanging there with a little peice to put two hoses together in it. Where does this attach to? Anybody know?
