Fuel Overflowing at Gas Pump and Check Engine Light on Toyota Celica

The Toyota Celica may develop an issue with the fuel tank inlet pipe causing fuel to spill onto the ground when fueling the vehicle.

The problem is a faulty 'check valve' in the filler tube, which normally prevents overfilling. The check valve is known to break off and fall into the gas tank. This can cause:

-OBD Trouble Code P0441

-Engine stalling or hesitation (Rarely)

The correction for this issue is to replace the filler pipe that leads from the gas cap to the gas tank
