Gasoline and water do not mix. That's why you'll often see gasoline set ablaze on top of a pool of water in action movies. Gasoline is less dense than water, so it floats on top. When water gets into your gasoline line in your vehicle, it won't mix--it will only cause you a headache. It will cause hesitation and knocking in your vehicle that can lead to permanent damage. Often, water seeps into the line when you leave your gas tank partially filled overnight and condensation forms in the tank. This will eventually seep into the gasoline line.
Go to your local automotive store and look in the gas line antifreeze products for a product containing methanol. Methanol, like water, is heavier than gasoline. When you add methanol, it sinks to the bottom of your gas tank where the water has collected and absorbs the water.
Purchase a methanol product.
Follow the instructions on the product's label to add it to your gas tank. Usually, it doesn't matter if you put the product in before or after a fill-up.
Wait 15 to 20 minutes.
Start your vehicle.
