How to Siphon to Remove Water From a Gas Tank
Water can condense within the gas tank of an automobile in humid climates. When the gas tank is running low, there is a larger inside surface area of the tank, where water droplets can form. Water accumulation in the gas tank is a detriment to the running of the vehicle, often taking the place of gasoline necessary to operate the car. Removing water from the gas tank can be done through the process of siphoning, or drawing up the liquid through a tube using atmospheric pressure.

Cut the tube to six feet in length. Unscrew the car gas cap, and remove the anti-theft screen, if your car has one. This screen is intended to prevent theft of gas from your car, but it will prevent the hose from reaching the bottom of the tank. Removing the screen may require removal of the gas input tube. See your mechanic, if this is necessary.

Insert one end of the tube down the car gas tank, and insert the other end of the tube to one end of the fuel primer ball.

Cut a second piece of rubber tubing three feet in length. Insert one end of this tube into the other opening on the fuel primer ball. Place the remaining open end of this second tube into the empty gas can.

4
Remove excess air in the tubes, by squeezing the primer ball. This will cause the fuel and water mixture in your tank to be sucked up into the tube and emptied into the gas can.

Tips & Warnings
Wrap electrical tape around the primer ball and tube connections to prevent gas from leaking out onto the ground and air from leaking into the device.
Pull the gas out of the tank, using only a pumping device; do not attempt to suck the gas out with your own mouth. This is a dangerous technique in which you will ingest toxins and cause physical harm to your body.
