What happens if you buy too much gas?

Normally, air flows through that tube while you’re filling and the gas keeps flowing as long as you hold down on the trigger. When that hole gets covered by gasoline (when your tank is full), a vacuum forms inside the nozzle and an automatic shutoff switch gets tripped, turning off the flow of gas with a thunk.

What happens when you fill up the gas tank?

When you pull up at the gas station, you should be able to insert the fuel pumping nozzle and hold it wide open until tank becomes completely filled.

Why does my gas tank smell when I stop filling it?

Another possibility of having a fuel smell inside the car becomes a fuel tank vent that’s not closing properly. The gas tank vent needs to open when you’re filling the tank to allow the air to escape. When you stop filling the tank this vent should close completely and seal the vapors inside the tank.
