Why does my gas tank keep backing up?

Another possibility? The gas could be backing up because of some kind of restriction in the evaporative emission control system (EVAP), which traps out gasoline vapours evaporating from the tank and keeps them from entering the atmosphere.

What happens if there is too much fuel in a car?

“If the vapours don’t get out fast enough and too much fuel is going in during filling, the fuel could back up,” says Willi Blum, a professor at the Automotive Business School of Canada at Georgian College in Barrie.

What to do when your gas pump keeps shutting off?

In that case, you can try adjusting the trigger setting to a lower notch, or squeezing it less with your hand, or possibly angling the fill nozzle to give the little breather hole a better chance of not getting splashed or submerged by gasoline.

The line going to the filler pipe is actually used to reduce the amount of vapor generated during refueling.

Why does the gas nozzle shut off when the gas tank is full?

This causes the spray from the nozzle to no longer be uniform (which is how we design our fuel fillers), causing turbulence in the fuel filler pipe, bouncing back, and momentarily blocking the venturi on the fuel nozzle. Also, one correction to Torch’s article is how a gas nozzle actually shuts off when the fuel tank is full.

Why does the fuel pressure spike when the float shuts off?

[This] line is also connected to the float valve that shuts off the canister vent line, so when the float shuts, the air path to the filler pipe also is blocked off, and the fuel going into the filler pipe causes a spike in pressure.

Why is there a hole in my gas tank?

The hole can be blocked as the level of gas in your tank rises, or even if a little splash-back occurs. The liquid blocks the airflow, the pump stops, the obstruction is cleared, and the pump will resume once you depress the handle again. It’s likely some cars are more prone to this than others.
