Customer Question
I have a 2004 F250...
I have a 2004 F250 FX4 Super Duty with a 7.3L engine. The water in the fuel idiot light comes on periodically especially when I step on the gas. I have had the fuel filters changed and put probably 30 bottles of fuel treatment in. It usually doesn't stall, but the glow plug light also comes on and a few seconds later, everything is fine. This started about 5 months ago and occurs almost daily now.

Thank you for the verify. I wanted to know for both engines use a different fuel setup.

On the 6.0L you have a module that sits next to the fuel pump on the rail, under the driver seat. That is the HFCM.

Take a 6mm allen wrench and remove the drain plug to see if there is actually water there or if the sensor is corroded from water that was in the system before. If no water, replace the manifold or the whole HFCM. You can buy the manifold only on eBay, but Ford only sells the whole unit.

It is a pretty usual problem on the 6.0L for that sensor to go bad on those trucks.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
