If the fuel pump pumps water, the engine will shut down and stop running. Once the engine stops, the fuel pump will also cease to operate. Below are relevant details: 1. If the fuel tank absorbs a small amount of water, the fuel filter can filter it out, but too much water is not acceptable. It can cause engine damage. If there is a significant amount of water, the damage is immediate. 2. If water enters the fuel tank, it is recommended to drive the car to a repair shop immediately after use for inspection. The fuel tank should be completely removed and cleaned, along with the fuel pump, fuel lines, and fuel filter. 3. Having water in the car fuel tank is very dangerous for the engine. The fuel pump may pump some water into the engine's combustion chamber. Since water is denser than gasoline and cannot be compressed, once water enters the cylinder during engine operation (water cannot be compressed), it can cause the engine's connecting rod to deform or twist, affecting the crankshaft, connecting rod, and piston. In the most severe cases, the piston may penetrate the cylinder head or even puncture the oil pan.
