How to Check for Water in Gas Tank?
Water in a gas tank could be a big problem. You may notice some of the most common symptoms of this condition.

- Engine hesitation – Engine hesitation is related to the behavior of your engine on the open road. When you want to reach the freeway speeds, your engine may show troubles and hesitations. This will be noticeable when you press the acceleration pedal, and sudden speed fluctuations will be there. This is because the water in a gas tank stops the engine to get enough fuel.
- Power surges – Power surges happen when an abrupt increase or decrease in power appears in regular conditions on the road. You may notice the loss of power when driving. In this case, the engine will lose power because a vehicle is not made to compress water when you accelerate it. As a result, the engine will noticeably lose power and acceleration speed.
- Corrosion – Corrosion is another sign that your car has water in a gas tank. When the water sits at the bottom of a tank, a rusty gas tank can be a result of this problem. This usually happens when the reservoir is almost empty. The pump will start to pull in the water that is on the bottom of the tank, and this will lead to rust formation.
- Sputtering – Sputtering, poor performance of the engine, and volatile change of the speed can be a result of the water in a gas tank. The engine will behave erratically, and it will give you trouble on the road.
All of these symptoms may affect your car in many ways. You will be unable to start a car or accelerate adequately.

How to Prevent Water from Getting Into a Gas Tank
First of all, you should know the reasons that lead to the water in a gas tank. There are many reasons for this situation, and you will notice some of the most common ones.
Your pump station may have bad gas pumps and they can sell fuel that is contaminated with water. In this situation, you should avoid these stations and go to those that sell high-quality fuel. 
On the other hand, if a gas station crew did not replace the gas cap after refueling, this may lead to a problem. The excessive water will enter the gas tank and it will mix with the fuel.
A gas cap is very important and you should take care of it. If it is broken and it does not fit anymore, you should replace it with a new one. In this manner, you avoid problems with the gas tank.
If a tank is loosely sealed, the condensation during the temperature change will affect the fuel. The water will accumulate inside the tank and it will lead to engine problems.
You should be aware of all these aspects if you want to prevent water from getting into a gas tank.
At the same time, be careful of where you refuel your gas. Stay away from old gas stations and areas that are prone to floods. By doing this, you minimize the chances of buying the contaminated gas.
When you do a car wash, do not remove the gas cap because this will result in many problems. The excessive water can enter the gas system and the car will not be able to start.
Your top fuel pump is also important. Check the condition of the fuel pump regularly and replace the worn-out parts when needed.
By doing all these actions, you will protect your car in the long run.
