Fuel Gelling
What are the symptoms of fuel gelling? I have a 05 6.0 that after a fill up began hesitation just of idle. Added some fuel additive seems to be better. All the bitter cold last week it ran fine. Water in fuel? Light did not come on?

Fuel pressure gauge is a 6.0's best friend, especially with the weather we have had here lately.
If you know your base line and it's running choppy, you will see a drop in pressure. Once it's gelled it's too late unless you add something like 911 red bottle.
I always tell the kid to double dose below 0*......it's cheap insurance and cheaper than injectors.
What fuel did you put in the tank?
Winter blend or straight #1?
Remember, # 2 starts to cloud already at 32*, and around 15* starts to gel
Choppy idle is a good sign of gelling, yes. Power will seem slightly down as well.
It's not unheard of to get a tank of something that is not blended as stated at the pump.

Well today i dove about a 1/4 out of it and it ran fine most of the day. Until way home, came to a stop bogged almost stalled like it was flooded then cleaned out hug black cloud of smoke never has done that before? No smoke during yesterdays hesitations. I am assuming winter blend as I am in Michigan.
