its probably the fuel vapor line
look for a hardline along the LH frame rail that goes up the firewall and back with the brake/fuel lines to the rear of the car, if its the same as an S13, it will be the bottom one, trace it all the way back to the fuel tank (if fuel is going thru it, theres a problem, as its only supposed to send the vapors thru the charcoal canister)
see if its that hardline, or the canister itself that the fuel is leaking from
youll probably have to drop the fuel tank to fix, but look before you take anything apart, it might be a simple fix (you can take out the fuel pump and use a flashlight and mirror to see whats going on inside the tank)
this advise is all based on an s13, but it should be *close* for an s12
