Just in case it wasn't asked or looked at, but how old is the gas cap? Could it be contributing to the problem and not the filler neck seal?

I have replace everything from the filler tube to the gas cap twice with new and used parts.  I am getting ready to take it all apart again and apply a thin bead of silicon around all the parts around the top of the tube to the cap unless someone has anymore suggestions.  Yes, I know the later years had that floaty-ball ball in there to stop this “defect” but I have the 83.5 with the foot wide filler tube that allows half the tank to slosh up it at every turn.
