Start by parking in a spot where you can jack up the left side of the car and putting jack stands under it.
Remove those black plastic belly pans under the drier’s side for the entire length of the car from rear wheel to front. One of the covers near the rear wheel is sort of squarish and it covers the fuel filter and pump outlet.
You will be able to get a peek at the filter and trace the fuel line to your leak. There may also be an evap recovery return line as well (I forget.). Fuel is pressurized by the fuel pump at the gas tank and will leak out of the line at any spot along the way to the engine’s fuel rail connector. There is a fuel pressure test port in the engine bay. You can relieve the pressure at that port. But with the type of leak you are seeing, the pressure is probably dropping after a few seconds of turning off the engine anyway.
If there is a crack or spilt, replace whatever is broken.
Sometimes a leak at the front up at the fuel rail connector can dribble down the line toward where you are seeing it.

That’s what it looks like to me. When there’s pressure it leaks from closer to the engine, when not then not. The fact that the car still runs and doesn’t lean out makes me suspect the connection to the rail. I’m just not sure what that connection looks like on a M113. I’ll do some looking around...
maw
EDIT: since you don’t know the car very well, I might start with the Service Valve and Injectors... fuel delivery may be the reason the car was sitting in the first place. This will give you some sense of what the connections look like, if you want to first make sure they are actually tight and haven’t been tampered with... https://www.google.com/aclk?sa=l&ai=...awQwg96BAgBEDs
