This vehicle runs erratically and sometimes stalls when its fuel tank is filled up but normalises after some time. What could be the cause?

Tank Pressure Control Valve
Fuel tank pressure or vacuum is controlled by tank pressure control valve. When fuel tank pressure reaches a specified value, tank pressure control valve opens and allows fuel vapors to enter EVAP canister. When fuel tank pressure becomes negative and reaches a specified value, tank pressure control valve opens and allows outside air to flow into fuel tank.
