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 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.
Why does the gas pump keep shutting off?
A majority of fuel systems have two primary fuel tank vents, one going to the evap canister (which is how the system displaces the air in the tank per the article you are referencing) and another going to the fuel filler pipe. The line going to the filler pipe is actually used to reduce the amount of vapor generated during refueling.
Is there a gas tank on a car?
The truth is that no car I’m aware of has any such device or capability. The refueling process on cars really hasn’t changed appreciably in around a century, at least on the car’s end. It’s still pretty much just a tube that leads to a tank. There is a cap on the end of the tube, and that’s basically it.

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.
Why does the gas pump keep stopping when my tank isn’t?
If it is just one pump that keeps stopping while all others work fine, there are several possibilities. The shut-off mechanism is hypersensitive. It barely stays open, getting shut by the tiniest of perturbations. The pump delivers too fast, causing splashing in the filler neck or in the tank. The fuel is foamy.
What to do when gas tank stops filling?
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. Also, make sure the compression cuff around the nozzle is fully in contact with the mouth of the fill tube, and compressed against it.

can’y re-fuel without pump stopping every gallon pumped,why? On some vehicles, on the filler tube from the neck to the tank, there is an air line which allows air out of the tank while the gas goes in. If it is blocked or broken the air not filtering out will cause the pump to shut off from back pressure.
How can I Fix my gas pump nozzle?
Try rotating the pump’s nozzle so that it is more horizontal to the ground. Try it one way, if that does not work rotate it 180 degrees to the opposite direction. Some pump nozzles are a bit touchy and will sense any splash back from the gas tank. What really helps… only put the pump nozzle half way into the tank.
Why does my fuel tank keep shutting off?
The fuel tank may become hard to fill and/or the fuel fill nozzle may shut off repeatedly while fueling. Our technicians tell us that various items including the fuel tank, vapor recirculation tube, fuel fill tube, or EVAP system canister control valve may be at fault. Proper diagnoses will be required to determine the exact cause of this concern.
