Gasoline Leak

I have a 1996 Saturn SL1 with 180,000 Miles. Last night upon returning from a short ride to the store I smelled gasoline after I parked the vehicle. I pulled the vehicle forward and found a small pool under the front tire on the driver's side. Upon looking, I noticed the car left a trail up the whole driveway about 100 feet.

Just was curious of the possible causes, fuel line, fuel pump?

The car is on it's last leg and I'm not sure if it's worth the repair.
