Is the fuel system on car sealed or can water get into it?

The fuel system on a car is typically sealed to prevent any water from entering. The fuel tank, fuel lines, and fuel injectors are designed to be a closed system to maintain the integrity of the fuel and ensure proper engine performance. If water were to enter the fuel system, it could potentially cause damage to the engine and lead to poor vehicle operation. Regular maintenance and inspections can help ensure the fuel system remains sealed and functioning properly.
