Water in Fuel will not go away

[ProjektF350]

So I have been getting the light about every 6 months or so. Usually as soon as the light goes on, I drain it. It came on about a month ago, I drained it. Came on again a few days ago, I drained it again. Came on within a day. Today I drained it and changed both fuel filters (draining it obviously). 3 min. into the truck running the light came on again....

*Edit* 05 F350 Dually 111,000 miles (if that really matters)

is it draining water when the light comes on? bad tank of fuel?

It drains a little water...Not to much (not anymore then the first times ive done it and the light went away for awhile. Im at about 1/4 tank now..Im going to run it down and go fill it again. I hope it goes away. I have a long haul ahead of me and I recently became "unemployed" so I hope its a cheap fix.

You can remove the side cover and clean it up in there. It usually means it's packed with debris when that starts happening.

Sent from my phone that somebody didn't help me get.

When you say the "side cover". Are you talking about the section where the drain screw is under the driver door?

Yes sir, iirc. Thats the hfcm. Horizontal fuel conditioning module.

So I decided to drain the fuel in the HFCM again today. I drained it, started the truck up let it run for a few. Shut it off and drained it again. Let it run for a bit and then put about 30-40 miles on it and so far no light. I added some Howes fuel treatment. Hopefully this works.

I am ordering some of the XDP diesel additive. Hopefully this keeps the light off.
