Okay, those hoses are interchangable at the AC end. All the ports on the
AC that are above the seam connect to the same internal volume, so you can
swap them around if that makes them fit better.

The thing to look at is the steel line that runs from the overflow tank
under the LF fender. That is what carries fumes from the gas tank back to
the charcoal cannister. That line is almost always clogged with internal
rust by now, making the evap system non functional. You can check it by
trying to blow in the hose at the tank end. If it's open, replace your old
hoses; if it's blocked, remove those hoses and cap the ports on the fresh
air elbow and the AC.
