Check the lines for the EVAP system. The EVAP system pulls gasoline vapor back to the engine to be burned instead of being released to the atmosphere. If you have a leak in one of the vapor return lines to the engine you'll get a gasoline odor. Since your '92 model is OBD I it may not trigger the check engine or service engine soon light.
