1998 Chevrolet S10 Question: What causes gas tank to make a poping sound?

at different times I smell gas fumes. I hear a popping sound come from the gas tank. I can be parked and it running and it pops or a few minutes after turning off engine I will hear a pop from the gas tank. Does anyone know why it is popping? Has anyone else had this problem? thanks Donna -
