Can you remind me what harm is done to a car when the gas tank is overfilled?
<br/> I remember once hearing a Car Talk caller who had problems due to overfilling, and so I have been careful to buy only the amount of gas I judge I need by my gas gauge, and not let station attendants "top it off".
<br/> My husband tells me this is ridiculous. But yesterday he pumped gas for me and actually let the tank overflow because the pump's stop-mechanism wasn't working. He says that no harm will be done if it happens only once, but I don't believe him.
<br/> My husband says he overfills the tank on his truck often, and it does no harm. But his truck has $0 resale value, while my car is pretty valuable. Who is right, and what remedial care do I need for my car after the overfilling?
