Under the tank there are a couple of breather pipes that can get kinked when you lift/lower the tank. This then causes a vacuum in the tank to be created when you run the bike.
The fuel cap itself should not be sucking in any air and if, after a run, you open the tank and get a hiss this is definitely caused by the breather pipes being kinked or blocked.
Lift the tank and have a look at then first.
