Water in fuel

[1LUCKSTONEFORD]

I have this ongoing problem with the water in fuel light coming on when the engine warms up with the water in fuel light coming on. Now, i change the fuel filter every 60days or approx 300 or less miles due to the conditions the truck is used in, and have never seen water at all in the fuel. even right after the filter is changed and the housing is drained the light is still coming on. Could this be a problem with th sensor mabye????

might want to get external one so you can be sure it is working, and added insurance.

Ok, but if i put an external filter on i just dont see that fixing the water in fuel light coming on. Or do you mean put a fuel/water seperator inline before the stock fuel filter. Also the light tends to come on when your puttin the power down more.

Anyone ever have to replace a water in fuel sensor possibly???

water in fuel sensors can go bad, a buddy had to replace one on his 97 last winter.

I have never seen any water at all when I drain my bowl every 9-12K when I change the FF. I would say you are on the right track by assuming it is a sensor, or a short in the wiring from the sensor. Time to crawl up on the 7.3.
