After pumping way too much gas into my '06 Tib, I found it leaking gas from the top of the tank. I did a thorough inspection, but I can't see where it is coming from. I removed the back seat and examined the fuel pump seal and it is not leaking there. After several days of diagnosis I discovered that the tank will not leak if I open the gas cap, but once I start and run the car, it will start leaking at that the top and flow down the left side of the tank no matter what slope I park the car. Does anyone know what part needs to be replaced and where it might be leaking?

Thanks for the tip! Anyone know if this caused by a component in the fuel system related to excessive pressure or a problem with the vapor canister?
