What to Do!
When you have fuel that is gelled, there are only two choices. One, warm the fuel up. This is generally done by dragging the piece of equipment into a garage. Or two, by using a product such as Thaw-It™ to dissolve the wax and reliquefy the fuel. Thaw-It™ contains two co-solvents to break down waxes in diesel and glycerin’s in biodiesel. Thaw-It™ will also remove (disperse) liquid and dissolved water in the fuel and fuel system, meaning Thaw-It™ not only helps with gelling, but also icing (when water in your fuel freezes, causing similar symptoms as gelling).
What NOT to Do!
Using gasoline, ethanol, isopropyl, or methanol is dangerous as it lowers the Flash Point of the fuel and will likely damage pumps and or injectors.
How to Use Thaw-It™
Remove the fuel filter and replace (if possible) with a new one. If you must use the old filter, try to pour out as much of the ice or gelled fuel as possible. Fill the filter with 50% Thaw-It™and 50% diesel fuel. (Do not fill with 100% Thaw-It™). Add 1 quart of Thaw-It™ per 50-gallons of fuel to the fuel tank(s). Allow to sit for 20-30 minutes, then start engine. Allow engine to warm before driving or operating.
Use Complete Fuel Treatment™ or Polar Flow™ to prevent fuel from gelling in the future. If you have water in your fuel system use EnerFuel™ to disperse water.
