What is the fastest way to ungel diesel fuel?

The fastest way to ungel diesel fuel is a combination of heat and an emergency de-gel additive, focusing on the fuel filter and tank, as additives alone take time to mix and heat thaws the wax crystals causing the gel. Move the vehicle to warmth, add a de-gel treatment (like Hot Shot's Diesel Winter Rescue or Fuel Ox Heat Bomb) to the tank, and pour some directly into a removed and warmed fuel filter before reinstalling, then let the engine idle to circulate the treated fuel.
