You can go into the back of the car and pull up the carpet. Behind the right side passenger seat there is a metal cap. Remove this. It will give you access to the fuel pump and some lines. Disconnect the lines. Go under the car and drop the gas tank (may require you to drop the axel as well). Follow the line looking for a leak.
PS I wouldn't do this. Too much work on this old of a car.
