85 Regal fuel leak

My dad's Regal started to leak gas today. I think its coming from the fuel line because I can see fuel under the driver side door frame rail leaking. There's gas on the ground right now and it is a bad fire hazard. What should I do?

replace that line as soon as possible. Not only is it a fire hazard, but it could cause the car to stall (the fuel pump could suck air from the leak) and get you in an accident.
