generic advice: check all fuel hose/line connections inside/under boot with engine running in Drive with Emergency Brake ON and someone pressing on the brake pedal; no smoking, save it for later. Change Fuel Filter as a last resort, might be stopped-up assuming it's old. If nothing is found, check into the Fuel Evaporative System for your specific model, you'll need a Service Manual for that.

Pull the spare tire and check the hoses connected to the fuel filter. You may have to remove the forward firewall carpet. It is held in with Velcro at the top.
Remove the trunk floor carpet. it is connected to a piece of foam. It will lift right out. Remove the battery cover and the two 6 or 8 mm bolts/screws holding the cover under the battery in place. You should then be able to examine the small fuel feeder tank and the fuel pump for leaks.
Remove the trim at the front l/h corner of the trunk. one or two of the same hex screws hold it in place. You should now be able to examine the rubber cose connecting the fuel cap to the tank and the vapor recovery hose for deterioration.

Check the foam pad under the fuel tank. On my 89, there was a pop rivet that stuck up from the rear axle arch and eventually wore a hole in the tank. There are also some one-way valves attached to the carbon cannister located ahead of the left front wheel (I assme this contraption was carried forward to the 91). If these valves are not functioning properly, they can put pressure in your tank. There should be no pressure in your fuel tank. Before digging into the fuel return system and charcoal cannister, read Kirby Palm's book on fuel tank leak/pressure issues.
