ok i was filling up my tank today and i gave the cashier a 50 well i filled my tank until the auto stop thing told the pump to stop... well i kept filling it up and all of the sudden gas starts streaming out at a good rate (not from the filler neck but from the tank. no hoses blew off or anything i was just wondering where in the heck it came spilling out from. any ideas, and yes i looked under the jeep and everything seemed ok.

 

theres a fuel overflow thing underneath, had that happen before

 

I had this prob once and it turned out the gasket on my fuel sending unit went out. I would fill it up and loose half a tank.

Just a thought
