Is it serious if a little rainwater enters the fuel tank?

[SanAllison]

If only a little rainwater enters, there is no need to worry. As long as the car can run normally without any power loss, it generally won't cause any issues. Below is an introduction to water entering the gasoline tank: 1. When the water content in gasoline is low: There won't be any problems. Gasoline has strong hydrophilic properties and can absorb moisture from the air. Besides water, there are many impurities in the gasoline tank. The water that enters the tank will mix with the gasoline. Even though the two have different densities and cannot fully blend, the water won't be drawn into the engine all at once. 2. If a significant amount of water enters: In this case, you can drain all the fuel from the tank and refill it with water-free fuel. If the car experiences engine shaking or weak acceleration, it's necessary to visit a 4S shop to clean the fuel filter, fuel lines, and injectors. Otherwise, in severe cases, the car may fail to start.
