P1457, Gasoline Odor

On my otherwise perfect daily 98 CX, I have had the CEL for P1457 about eight months, I understand it is an emissions leak somewhere. My question is what specifically should I be looking for? I notice a rather heavy gasoline smell when it’s full coming from under the hood area.

that is a evap canister fault.Check the charcoal canister.Could be gas leak from tank to

very common to shit the bed on these being that old.
