Is your carburetor electronically controlled? Although its not specifically part of the fuel system, a plugged catalytic converter is also something I'd suspect.
I had a similar problem on another car, in turned out to be some debris had gotten between the venturi on the carburetor(as your looking at the top of the carb that's the the little round deal in the middle of it) and the wall of the carb so it messed up the airflow and the onboard computer just kept dumping more and more gas in. That may be all it is, although that is just a total shot in the dark.
