Question

Can gas line antifreeze, which is alcohol-based, be used to remove water from a gas tank?

Answer 1

if the car is running roughly at low fuel levels, it's more likely due to sediment in the tank than water. the easy answer would be to stop letting your tank get that low (this goes for any car), but you'll still have to deal with the bad fuel pump issue sooner or later. i recommend running some fuel system cleaner and a little bit of alcohol through your next 4 or 5 fuel tanks. hopefully this can clean your pump out enough that you won't have to worry about it until you get rid of the car!

Answer 2

It bond with moisture to help it move on thru the system, without damaging the engine. However it only will help with very small amounts of water. If a large quantity of water has gotten into the tank, you will probably have to drain it and let it dry before refilling. All gas will have some water in it. Most gas has additives to do the same thing as fuel line antifreeze.

Answer 3

How much water are you talking about? If someone has put water in your tank, you might have to drop the tank and remove the water. On some cars you can enter the tank thru the vent line, and pump the water out. In some cases, the water might have entered your exhaust system. Which means you have to open your exhaust sys to warm the engine to operating temperature. Once the car is running you can then reconnect your exhaust and blow the water out of it.. . Good Luck

Answer 4

Antifreeze will not remove water from your gas tank, it does boost octane and help the car run while the water in your tank is used up as you drive.
