water in fuel
 

The water in fuel light is on in my 90 CTD. I drained the fuel out of the filter like the book said, yet the light is still on. The previous day I washed under the hood, yet when I started it the light did not come on. I also had filled up the truck a few days before. Anyone had this problem? Could the sensor be bad and taking a false reading? Thanks:humm:
