Will the Fuel Tank of a Flooded Car Get Water Inside?
1 Answers
The fuel tank of a flooded car generally does not get water inside, whether the water has just submerged the wheels or the entire body. This is because the fuel tank has excellent sealing and a certain degree of pressure resistance. Even gasoline fumes are not easy to permeate out, let alone water. However, there are still some oversights that can cause water to enter the fuel tank. Fuel-related issues: Due to fuel quality and storage problems, accumulated moisture in the fuel itself can lead to water ingress. Air entering during refueling: Air that enters the fuel tank during refueling can condense into water. Whether the fuel tank cap is tightly closed: During car washing or rain, water can seep into the fuel tank through an improperly closed fuel tank cap. Hazards of water in the fuel tank: Since water is denser than oil, it will gradually separate and settle, accumulating in the bends of the fuel lines or the filter. Besides corroding the fuel lines and causing rust, it can also disrupt the normal fuel supply of the fuel system. Under normal temperatures, fuel can dissolve some moisture, but as the temperature drops, the solubility of water decreases accordingly. Therefore, issues caused by water in the fuel tank become more pronounced in winter. When the temperature falls below the freezing point of water, it can freeze and cause fuel line blockages, rendering the engine inoperable.
