Why can't the fuel gauge be filled up?

[VonEvelyn]

Here are the specific reasons why the car fuel gauge cannot be filled up: 1. If the refueling speed is too fast, it will generate expanding steam, and the gasoline vapor cannot be released in time. If the carbon canister solenoid valve is closed at this time, the gasoline vapor in the carbon canister will accumulate more and more. After the gun jumps, the gasoline vapor will push the gasoline stored between the fuel filler and the fuel tank out of the fuel filler, causing choking, but the fuel tank is not full at this time. It is necessary to check the working condition of the carbon canister and the carbon canister solenoid valve. 2. There is a problem with the oil dipstick in the fuel tank. It is necessary to check whether the oil dipstick is damaged. 3. The fuel gun is inserted too deep. The gun jumping is the small hole at the fuel gun mouth, which will jump and cut off the fuel when it cannot suck in air.
