Where's my MPG going?

There is no such thing of gas going back into the pump. Once the noozle flapper is closed, no gas will go back into it. I used to work at a gas station and there are no pumps that suck gas back into them. This is why when you have completely paid for your gas and the pump is turned off, you should re-insert the noozle and give it a squeeze to release the fuel(that you paid for) that was left over in the hose. But it will not go back into the pump.
