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

It can, yes.

What does it mean if it does not?

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.

"It's definitely sucking"

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

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