My Water in Fuel light has been coming on again after being off for months. I haven't driven the truck much as it's basically for towing my 5th wheel. To recap, I originally had the tank drained and drained the filter half a dozen times and never ever found any water. Today I replaced the WIF Sensor and a new filter. Thought that had fixed it for about a minute and the light came on again. Sure wish I knew what was causing the light to continue to come on intermittently. I haven't seen any posts where this is happening to anyone else. The truck has always run great. Any help would be appreciated.
