The tank is under pressure due to gasoline vapor , so if you here a rush of pressure when fueling don't worry about it.
Testimonial: "Thank you for your assistance, how do I know if the pressure build up is excessive, or within the "normal" range? It is drastically more than it usually was, is there any possibility that the system is not breathing properly, or a possible block in the return pipe?"

You may have a defective relief valve in the gas cap. Remember hot days cause much more pressure.
