Under the car, just forward of the fuel tank, on the passenger side, it appears to be the fuel pump? There is a plastic shelf under the pump and it is leaking gas when I drive - it does not leak when the key is off. Oh, the year is 1989, but the drop down only goes back to 1990. Thank you,

it could either be the fuel pump, the fuel filter or one of the hoses. all of these are together in this one location. once the car is raised on a lift you can see what's leaking.
