I own a 1994 Explorer and I've noticed that when I fill the tank up, gas
leaks from what appears to be the middle of the vehicle. The first time I
noticed it, I thought the attendant had over done it in terms of filling it,
to get a round number $$, but since then I've done it myself and once the
gas nozzle automatically caused the gas pump to stop, I stopped, but it
still leaked. I would say it was about a 1/2 gallon that was left under the
truck.

I don't know whether this is related or not, but I figure I should give as
much information as I have; the truck sat for about a year and when I got it
back on the road again, I noticed the gas gauge didn't work. The leak only
happens at fill-up, I see no evidence of gas leaking once I leave the pump.

Any help would be greatly appreciated.

Thanks in advance.
