Water in gas tank

Question:

The gas door and cap were accidentally left open when going through a car wash. The tank had just been filled up and it looks like there is a metal door that is closed unless a fuel pump is inserted. What problems may occur and is there something that should be done?

Answer:

Karen,

I would put a bottle of “Dry Gas” or similar gas line treatment that removes water, into the tank immediately. The alcohol in the treatment removes the water from the gas tank. If you experience sputtering, or poor performance after the treatment, I would have the tank flushed at your mechanic. More than likely, not much water entered, since the tank was full, and the flap in the filler neck should have prevented some of the water from getting in.
