Normal Power Service (white bottle) will not ungel fuel.
Get Power Service Diesel 911 (red bottle) or Diesel Melt Down from FPPF or equivilant product. Anti-gel is not a de-gel. You need to de-gel or ungel your fuel.
First off, it is likely gelled in the fuel filter. Plug in your block heater over night, and put the truck in the garage if possible. Enough heat will reach the fuel filter to ungel the fuel in the filter.
Second, dump the Diesel 911 or Melt Down in the tank. If possible, park the truck in a heated garage overnight. You just have to get things above 35 or 40 degrees really.
In the AM, once you get the truck running, dump in a good anti gel, like Poweer Service Diesel Fuel Supplement (white bottle) or AMSOIL Cold Flow or equivilant product. Go fill the truck up if it is low on fuel, you'll want to dilute that 911 as much as you can now. From now on, treat every tank with anti gel if you are in cold temps.
If you can't find an anti gel, I can ship you a case of Cold Flow. Most truck stops and heavy truck repair shops should carry antigel and degel 911 products.
