Symptoms of Water in Gas Tank and How to Fix It

​Having a car means that you have a lot of responsibilities, and therefore, you have to look out for any signs of possible breakdowns. One of the things that can really degrade your car’s engine performance is having water in your gas tank.

And, most of the people actually don’t even mention this kind of problem until it’s too late. Also, if you have water in your gas tank, your car will act weird and later on, your engine will definitely be damaged.

Luckily, we are here to discuss everything about this car problem, so that you can prevent it from happening to you. Let’s begin.

Symptoms of ​Water in ​Gas ​Tank

First, let’s talk about the most common symptoms that you can acknowledge if you have water in the tank.

1) Failure to start the engine

As we all know, your car’s engine works on fuel and therefore, you need fuel to start the car. However, if your car won’t start at all, there might be some water present in the fuel tank.

Usually, the water in the tank needs to be above the piston that is inside your car’s cylinder. This means that the piston won’t be able to complete the rotation and therefore, you can’t start your car at all.

If you notice this kind of problem, it is recommendable to check the fuel tank and see if there is any trace of water in it.

2) A decrease in engine power

If there is water inside your fuel tank, your car will lose its engine power. However, this is a bit harder to notice since your car’s engine will lose its power slowly over time.

Anyhow, you will definitely notice that something is not right with your car as the vehicle’s mileage is going down. In that light, you should always check for the water in the fuel tank since you don’t want to damage your engine.

The whole process of decreasing engine power of your car will start because of biodegradation of the fuel, which will decrease your car’s power.

3) ​Acceleration Problems

Now, most of the cars have pretty good acceleration power, but they can all have troubles accelerating if there is water in their tank. The obvious sign of poor acceleration is when your car needs more time and force to do so.

That is possibly the most common symptom of water in tank problem. This happens because your car actually needs gas to accelerate, not water. Therefore, it will have plenty of troubles accelerating if there is water in the tank.

4) Splutter of the vehicle

Your car will definitely start to splutter when you hit the gas pedal if you have water in tank problems. This is caused by water entering the fuel system and being injected into the engine which is actually pretty bad.

The engine will not have the right kind of fuel to accelerate the car and you will notice that your car is spluttering.

So, it's time to remove water from gas tank.
