Cant understand your problem corectly.

Every car fuel tank has pressure build up to push the fuel to the engine thru fuel pump. If petrol cap is opened and heard some hissing its pretty normal. Leave it open for a minute and then refill if you think its not taking more fuel. Lets the car be running when u open the fuel cap in petrol station, so that pressure can be remove faster.
