Fuel Leak, please help?

[CityGuy24]

Ok, so I filled my 2000 Corolla up last night. I did not top it off. I let it fill until the pump kicked off. I then get on the interstate headed home and I make it about 10 miles when someone flags me down and says I am leaking gas. When I pull the car over gas is all over the underside behind the fuel tank and is dripping everywhere so I really can't tell where it might be coming from. I decide to call a tow truck, and it just so happen when the car is lifted at a 45 degree angle, gas starts running off the top of the tank. This happened about 9pm last night and I had to work this morning so I have not had a chance to look at it yet. Does anybody have any idea what may be leaking. I am guessing it could be a fuel line, or the seal on top of the gas tank? Or could it just so happen the pump overfilled the tank a little? Just let me know what you guys think. Thanks!

Possible that the pump overfilled the tank, but more likely you have a bad cutoff valve (top of tank), cracked fill tube, blocked vent tube, or cracked seal around the fuel pump assembly. Could also be more sinister, like a cracked fuel tank. Leaking fuel line is also another possibility.

Hard to say without pulling the tank down and having a look at it. There are a number of plastic fittings and valves at the top of the tank - any could contribute to a leaking tank, but given that gas ran out when the car will jacked up in the air - could be just about anything at the moment.
