Abstract
A heater system for a diesel fuel filter comprises a housing, a self-regulating electrical resistance heater element of positive temperature coefficient of resistivity arranged in heat-transfer relation to thermally conducting components to form a heater means, the heater means being mounted within the housing so that diesel fuel passes directly over and around the various thermally conducting components of the heater means to elevate the temperature of the fuel as it passes to the filter to deter clogging of the filter by paraffin or other fuel components which may solidify in the fuel at lower temperatures, and electrically conducting means which extend from the housing in sealed relation to the housing for electrically connecting the heater means to a source of electrical power.
