gas leak on 2001 Isuzu Rodeo Sport

When I put gas in, it is leaking out from under the suv. Has anybody else had this problem.

Hopefully the tank hasn't suffered damage due to road contact with debris. It needs to be checked out as soon as possible as it could be dangerous. It will set a Check Engine Light soon for Emission Control Evaporation emission failure.
The gas leaking will leave a stain so it should be easy to see where the leak is from. Removing the gas tank and reinstalling takes about 1.5 hours.
