How do gas pumps know when the tank is full?
When gasoline flows through the nozzle, it passes through something called a venturi, which is a tube with a narrow throat that changes the speed and pressure of the liquid passing through, creating a vacuum. As your gas tank fills, the fuel level rises until it covers the hole at the end of the nozzle.
Why doesn’t my gas tank fill up all the way?
An early shut-off can be triggered if the fuel is not flowing freely into the tank. Angling the fuel nozzle into the fill pipe differently usually does the trick. i.e. Holding the handle up instead of letting it hang down, or rotate it a bit in the fill tube mouth.
How do you fill a fuel tank?
Open the fuel filler door. Insert the gas pump nozzle. Fill the tank. Stop when the automatic shut-off activates. Don’t overfill the tank. Wait a minute or two to let all the fuel drain into the tank. Remove the nozzle and close the fuel filler door.
What is a tank filler neck?
A vehicle’s fuel tank filler neck is a tube that attaches to your fuel tank and your fuel filler inlet. This is the part where you put the nozzle of a gas station pump when you refill your fuel tank. The filler neck makes refueling easy and efficient.
