The first cause of water in the gas tank could be due to the poor quality of the gas at the gas station. Or the car could have been refueled in the rain and water could have entered the gas tank through the pump.
The second reason is that the car has to run or leave the car flooded, especially during the rainy season, when the streets are flooded without a method to protect the gas tank cap.
Temperature and humidity also cause condensation of water vapor in the tank. In this case, the amount of water that appears is not much but it is not without danger.
