WATER IN FUEL LIGHT

I just purchased my 2000 7.3 F350 a few days ago. It has the water in fuel light on. I drained the separator with the yellow valve and changed the filter. Do I need to reset something to get it to clear or do I have a bad sensor?

You might have a gunked up fuel filter assembly - Drain it again, take of the filter, and clean it up. Occasionally, they will get so bad that you have to take them off, dissasemble them, and clean them with brake fluid.

The crud in the bottom could be interfering with the sensor.

Water is fuel light

Thanks, The old filter was nasty and the housing was dirty. I will try to clean it up tomorrow. Where exactly is the sensor in the separator? Thanks for all the help!

If I am not mistaken, the fuel heater thermostat and water sensor are together, at the base of the bowl, in the back just beside the fuel drain assembly. There is on connector on the back of it.
