What to Do If a Little Water Gets into the Fuel Tank?
2 Answers
If water enters the fuel tank, it needs to be drained completely, refilled, and the engine oil should be replaced. Below is relevant information about water entering the engine: 1. Significant water ingress in the engine: If a considerable amount of water enters the engine but does not affect normal driving, though the noise may be louder, it could indicate a small amount of water in the engine oil or fuel. In this case, the engine oil needs to be replaced, and related engine components should be cleaned. 2. Reasons for the car stalling in water: If the distributor cap gets wet, it loses its normal ignition function. Water entering the engine's air filter increases intake resistance and may lead to water entering the combustion chamber, preventing the spark plugs from igniting. Restarting the engine under these conditions can easily cause hydro-lock.
I've encountered the issue of water getting into the fuel tank several times while driving. It's not difficult to handle, but requires caution. Remember not to start the engine immediately, as water entering the engine could damage internal components, leading to expensive repairs. The first step is to park the car on level ground, then use a manual fuel siphon or ask a friend to help remove the water-contaminated fuel from the tank. After that, add some fuel water remover to absorb any remaining moisture, then fill up with fresh gasoline and take a short drive to test the engine's performance. I usually check the fuel tank cap for proper sealing after driving in rainy conditions to prevent water ingress. Safety first—if you notice any unusual engine noises after treatment, it's best to visit a repair shop. To keep our cars durable, these small details shouldn't be overlooked. Long-term water contamination can also lead to corrosion and increased fuel consumption.
