Mine's an '00 and no leak as far as I know. Yet.
I doubt Prime would stop it from leaking down the vacuum line (if it was already leaking in On or Res). That would just turn the gas on for both lines

I just learned something....and I remember this coming up with someone a couple years ago too.
I'm thinking an aftermarket petc0ck would be a good move, in light of this...
