AARGH Fuel Leak

[Electron]

About a day after filling up the tank in my Supra (I had only been putting about 1/2 tank in before) I see a distinctive tiny puddle below the rear passenger side of the car. Premium is leaking out, and about 1/2 of the gas tank protective cover is wet with slowly dripping fuel. I don't know why this would be. Help would be welcome and rewarded. I'm worried about driving the car, even though the wet area is fairly far from the exhaust.

I have a Mk3 fuel tank which I believe to be in good condition, but it's gone Monday. You pull it, and it's $25. (If I pull it, it's $50. -- assuming that I have time to pull it before it gets hauled away.)

Edit: The filler neck is NOT okay, it's been squashed.

I'll be there on Saturday with my car, but my problem may be the filler neck (given where the leak is).
