At low temperatures paraffin drops out of diesel fuel. This paraffin clogs the fuel filter, making the cranking and the run of the vehicle difficult or even impossible. The Fuel Heater warms up the fuel before the filter, keeping the paraffin in liquid phase and assuring the cranking and the running of the vehicle at low temperatures.
