Dangers of Water in Your Fuel Tank

A common problem that many people face is water in their cars' fuel tanks. There are two view points on this, one, which says that having water in your cars fuel tank can be very dangerous. While on the other hand there are those who claim that there are not any dangers of having water in your fuel tank. The reality is that having water in your fuel tank may not be an immediate danger but it could pose a danger down the road. The causes of this are could involve fueling your car at gas stations that are prone to flooding where water can enter their underground tanks or by constantly emptying your fuel tank. There are two primary dangers that can occur from having water in your fuel tank which include:

It could put a hole into your fuel tank: Water is heavier than gas, this means that when you are driving over time the water will sit at the bottom of your fuel tank. At some point this water will corrode through the fuel tank creating a hole. When this happens it will cause fuel to leak out of your fuel tank causing a fowl gassy smell to seep into your car.

It can cause engine problems: As the water is building up with in your fuel tank it can slosh around in the tank when you are driving through a bend or hills. When this happens the water can mix with the gas, entering the fuel line leading to a misfire in the car. You see whenever water and the gas mix together this can change the overall fuel mix causing a misfire. If you are on flat terrain this could cause the engine to seize up since there is no way of forcing the water out of the fuel. For those cars with carburetors this can cause a problem because the float chamber can fill with water. In addition it can increase the amount of water in the fuel filters affecting the overall engine performance.

Clearly water in the fuel tank can have a long term effect on your car, some of the common problems that it can cause are a hole in your fuel tank and it could cause you engine problems. While this is not a major threat to you or your car over the short term it could cause your vehicle long term damage.
