May want to check this - it's for different years but may be similar:
2003-2005 6.0 Water In Fuel Lamp Illuminated:
Some trucks may exhibit a water in fuel lamp that continues to illuminate after draining the water separator, or a flickering water in fuel lamp. This may be due to sediment build up in the water reservoir or a computer calibration issue. Check the electrical connections at the fuel pump assembly for damage or corrosion. If the harness is damaged, repair or replace it as needed. There is a jumper harness available, part number 6C3Z-9F759-A*. Remove and fuel manifold from the fuel pump and inspect for debirs inside, and clean as needed. If the sensors inside the manifold ot the sensor pins are corroded, replace the WIF sensro (fuel manifold) with kit 6C3Z-9C264-A*.
*The fuel filter heater has been deleted from the fuel manifold. When installing the updated harness or manifold, also remove the fuel heater fuse (2003/04, 30 amp fuse #105 under the dash; 2005, 30 amp fuse #7 under the hood). If the light is on intermittently or flickers, or will only go out if the computer stored codes are cleared, the computer may need to reprogrammed.

Edge CTS keeps WIF light on all the time?!!!

Here's a video showing how the Water In Fuel light on my 6.0 liter 2003 F250 is coming on due to the Insight CTS device I installed: Insight CTS water in fuel issue by Daniel Odio-Paez on Socialcam - Nov 28

I emailed Edge about the problem, but they believe it's limited to just my vehicle (!!!). They wrote, "I think this issue may be something we can't fix as we have to pull data to view the parameters and the act of pulling data doesn't typically cause any issues whatsoever."

If you have installed an Insight product and your water in fuel light is on, please test it as I did in the video above. If yours is doing the same thing, PLEASE email the folks at Edge, at tech@edgeproducts.com so they know I'm not the only one with the problem. Maybe they'll figure out a way to fix it if they realize there are others with the same problem, since they don't seem to care too much when it's just me.
