If it is a throttle body fuel injection systemthe fuel pressure regulator is built in to the throttle body itself, it is not a vacuum operated regulator , it uses a spring and atmospheric pressure to regulate fuel pressure. have you tried smelling around your charcoal canister, no particular reason just a place that comes tomind that could easily be forgotten.
