Removing water from dirty gas!

[peter24]

Is it possible to remove the water from the contaminated gas. I recently took my car to the workshop, and they told me that the fuel tank is contaminated with dirt and water. I am sure about the dirt that it can be removed, but what about water?

Many workshops promise to deliver the fuel tank completely clean if the gas is contaminated. But it is not possible to remove the water from there as the alcohol present there attracts the water and doesn’t matter how much you clean it, it wont be helpful in removing the water from inside.
