ABSTRACT:
A fuel heater adapted to mount in series with a diesel engine fuel line comprises a metal pipe having a resistance heater wound around a first straight portion of the pipe containing a fluid deflector dividing the first portion into a plurality of fluid passages. A U-shaped bend is formed in a second portion of the pipe upstream from the heater. The pipe is flattened to less than half the normal diameter of the pipe in the bight of the U-shaped portion and a bimetal disk thermostatic switch is mounted on the flattened wall of the pipe. When the ambient temperature of the fuel is below a predetermined temperature and is flowing through the flattened pipe, the switch activates the heater, but if the fuel stops flowing or increases in ambient temperature, the switch cuts off the heater.
