Did you try filling at a different service station. Your issue seems pretty rare, but other have reported it.

This happens when the tank ventilation system gets clogged, or the bottom of the fuel tank is bent inward. When you fill the tank it displaces air as the fuel goes in. It acts like its full because it can't vent the air out of the tank

Fuel gauge is inaccurate. Just keep filling tank till it takes no more. And knowing the gas mileage you get on the car and fuel tank capacity, set the odometer and when you calculate that you are getting close to the bottom, get some gas.

The problem is more then likely charcoal canister vent valve (solenoid) ,emission system hose's ! How to fix car that will not take Gas the pump keeps shutting off

SOUND LIKE EVAP CONTROL SYSTEM NOT WORKING.COULD HAVE STOPPED UP FUEL SOAK EVAP CHARCOAL CANISTER.OR THE PURGE SOLENOID NOT WORKING ALSO GAS CAP COULD BE FAULTY.HAVE THE EVAP SYSTEM CODE SCANNED.WHEN PUMPING GAS EASE THE GAS SPOUT OUT JUST A LITTLE SO YOU CAN PUMP GAS IN TAKE.REASON CAR WONT ACCEPT GAS BECAUSE EXCESS GAS VAPORS CAUSES PRESSURE TO BUILD UP IN FUEL TANK IN WHICH WILL KEEP GAS FROM BEING PUMPED IN FUEL TANK.

unfortunately most fuel tanks are made so you can no longer siphon gas through the fill tube. if you want the fuel that badly you could disconnect the fuel line from the fuel filter and wait for it to drip out.

inside the tank itself (at the bottom of the filler) ther is a spring loaded valve. when the valve starts to stick, the fuel cannot get around it causing the gas to stop flowing. what i would do is remove the tank and check that valve. replace if sticking.

Most cars and truck nowdays show the tank empty when you start it. Then it slowly advances to the correct level of fuel in the tank. You can try and use some fuel additives like Gumout or Valvoline that clean the injectors and other fuel sytem parts. You can get a buildup of tarnish in these parts and this can cause slow readings. If this was the case it should improve after a few tank fulls of gas with the cleaners added. The guage could also slowly be going bad. The newer style guages are connected to the fuel pump and you will need to replace the whole unit if this goes out on you. Keep in mid that when the fuel pump quits, it quits, usually without much advance notice. If the car starts sputtering and does not have full power, this will hint at the fuel pump going bad. If your car has over 100,000 miles on it, you might want to think about preparing to change the fuel pump, these seem to want to go out shortly after 100,000 miles, but you can get lucky once in a while and it can last longer. Keeping your tank at least half full with clean gas is a big help, the gas keeps the fuel pump cool so it last longer!

This sounds overfilled to me. Liquid should not get to the canister, only vapors, look for exactly what separates and stops liquid fuel, somewhere along the vent line... Sometimes on top of fuel tank.

BUT, it sounds like you are seriously overfilling. Gas comes out of the ground cool, then heats up in your tank. Put much less fuel in gas tank.

Fuel no longer lubricates anything, so no issue with full time LPG, but starting is commonly an issue, and most designs start with gas and cross over automatically to LPG, after warmed up.

Evaporator vent silenoid at rear by gas tank is most likely stopped up. Is the check engine light on? If so, take to Auto Zone and get them to scan it for free. Get codes only and post them.
