As a mechanical engineer with extensive experience in automotive systems, I can provide a detailed explanation of what happens when water is introduced into a gas tank.
Firstly, it's important to understand that gasoline and water do not mix. Gasoline is a hydrocarbon, which means it is a compound made up of hydrogen and carbon atoms. Water, on the other hand, is a polar molecule consisting of two hydrogen atoms and one oxygen atom. Due to their different molecular structures, gasoline and water repel each other and form two distinct layers when combined.
When water enters a gas tank, it tends to settle at the bottom because it is denser than gasoline. This is where the potential problems begin. There are several scenarios to consider:
1. Gravity Feed Fuel System: In older vehicles or some off-road vehicles that use a gravity feed system, the fuel pump may draw water into the engine along with the gasoline. Since water is not combustible, it will not be able to be ignited by the spark plugs. This can lead to a condition known as "hydrolock," where the water in the cylinders prevents the engine from turning. This can cause severe damage to the engine, as the pistons may bend or break when they encounter the non-compressible water.
2. Fuel Injected Engine: Modern vehicles with fuel injection systems are less likely to draw water into the engine because the fuel pump is typically located higher in the tank, away from where the water would settle. However, if water does get into the fuel system, it can cause damage to the fuel injectors. The water can corrode the injectors and cause them to malfunction. Additionally, water can disrupt the fuel's ability to atomize properly, leading to poor combustion and reduced engine performance.
3. Corrosion and Contamination: Over time, the presence of water in the fuel can lead to corrosion in the fuel tank and fuel lines. This can cause leaks and further damage to the fuel system. Moreover, water can also contaminate the gasoline, leading to a lower quality of fuel that may not burn efficiently.
4. Fuel Pump and Filter Issues: The water can cause the fuel pump to work harder than it should, potentially leading to premature failure. Additionally, water can clog the fuel filter, restricting the flow of fuel to the engine and causing it to run poorly or not at all.
5. Emission Control Problems: Water in the fuel can also affect the vehicle's emission control system. The catalytic converter, which is designed to reduce harmful emissions, can be damaged by the water as it is not designed to process non-combustible substances.
To prevent these issues, it is crucial to ensure that water does not enter the gas tank. This can be done by:
- Keeping the gas cap tightly sealed to prevent water from entering through the filler neck.
- Regularly inspecting the fuel system for leaks and repairing them promptly.
- Using a fuel additive designed to remove water and prevent corrosion.
If water has already been introduced into the gas tank, it is advisable to have the vehicle inspected by a professional mechanic. They can drain the fuel tank, clean the fuel system, and replace any damaged components.
In conclusion, putting water in the gas tank is a serious issue that can lead to a variety of problems, including engine damage, reduced performance, and costly repairs. It is essential to take preventative measures and address the issue promptly if it occurs.

If fuel delivery system is gravity feed system, chances are the water will be the first to get into the engine[as water will be in the bottom of the fuel tank] and this is something undesirable for an engine. It won't work, if its a fuel injected engine water in fuel will damage the fuel injectors.
