Question back pressure!

it is a 190e car

when i open the gas tank cap,i get a rush of air from the the gas filler area-is this abnormal indicative of some impending problem or is just normal because the fuel injection system is pressurised?
the only notable symptom is an intermittent loud buzzing from the the electric fuel pump.
