Hope this is any easy fix! The water in fuel filter light came on. Replaced the Davco paper fuel filter. The light went off and came back on. Drained lots of fuel from the water separator and replaced the fuel filter again. The light will not go off and there are no codes. I have not driven out of the garage after the 2nd filter replacement. Not sure if that could cause other damage. Any help would be appreciated. Not sure what to do next.

The water-in-fuel sensor has likely failed. It's a simple replacement, if it doesn't break off. They usually behave.

The new sensor worked and was easy to replace. Hino sells them for over $100. I saw others that look the same for about $30. I went with the expensive hino one to be sure it would work.
