Depends on your fuel blend as to what temp. it will gel. If it has try adding Powerservice 911 to your fuel tank and filter as per the directions. You should also get the vehicle into a warmer environment if possible (garage). You can change the filter if that is all plugged up and fuel flow is restricted.

Good luck! Tim

911 and change fuel filter would be my SOP. Most gelling occurs in the fuel filter, 911 will clear anything else.

I carry one of each with me during the winter months

23 should be fine even for straight #2. Put in some Power Service in the white bottle or other anti-gell aditive for some peace of mind and you should be good to atleast the low teens.

If she does jell on you get her in a warm enviroment if possible, change the fuel filter if possible, definatly dump a bunch of additive in there(I would start with just a ton of regular additive). Keeping the truck running will put heat in the fuel, mix your fuel and additive, and burn the crap fuel out. Fill it with known good fuel too. If the fuel is very nasty and none of the above works pump out all the fuel you can, fill her with fresh, let her run, change the filter and keep her running and dumping fresh fuel and a heavy additive mix in there.

Once you gell you realy should change the filter ASAP even if you get her running OK.

JMO

How do you know if you gell and or possibly bad fuel? Truck can run like crap(ussualy low power, could be stalling), may throw a code(light) and when you try the water drain on the fuel filter(always drain in a clear container so you can inspect) you may get water, or even nothing if the thing globs up solid on you. Symptoms may also be intermitent.

It can happen all of a sudden when you get a cold snap and let your truck sit or it may happen more gradually if you get some dirty fuel(or fuel that is very cleansing and knocks all the crap in your tank lose and into your filter) If its a sediment problem then keep additive package high, and keep changing the filter as needed and adding fresh fuel.

Also be carefull when working with cold fuel. If the fuel is liquid it may still bet 10*. 10* liquid on a cold windy day on your hand can be bad news.

If you get crap fuel hopefully you have your recipt and can go raise hell at the station you bought fuel from.

So what has everyone else done if they have had a truck gell on em? Last time I had the issue I was about to put a few gallons of kerosene in the tank instead of diesel but I was able to get her running fine.

Just put in a double dose of anti-gel, let it sit for a bit, and changed the fuel filter. Fired right up and not another problem.
