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

    expansion and contraction. you have a problem with the evap system that is allowing this to happen.

    take it to a shop and have them check this for you.
