This is my first diesel which is a 2013 3500.
I’m on vacation in Alabama and filled up when I arrived.
A day later, the water in the fuel light came on, so I drained off both filters, and they were still on.
The bottle I drained into after sitting does not show a separation of water and fuel.
Up in PA, the diesel is usually very green tint, and the fuel drained here is more amber.
Other things are in play as I run Hotshot secrets everyday treatment religiously.
The truck runs 100% normally; the fuel filter has about 2500 miles on it, and the truck is at 132k.
The sensor and wire look ok but are 10 years old and original.
Any input is welcome as we pull the 20k fifth wheel and head home tomorrow.
The light came on yesterday, and I don’t want a breakdown.
I think I might have a sensor failure.
The only code in the engine is water in fuel detected.
