Sucking Sound

Should a sucking sound come from your fuel tank after you have been running the car and remove the fuel cap?

I'd look into your fuel tank ventilation. I suppose I might expect a small vacuum, especially if the fuel is low, but it sounds like your tank might be building up too much pressure.

Would this be a sign of a fuel pump going out?

It's the sound of more money being sucked out of your wallet.
