Abstract
A heater device of a diesel fuel filter may include a heater housing inserted into a diesel fuel filter, and a heater portion inserted into the heater housing. A plurality of flow-path regions may be formed in the heater portion such that heated fuel passes through the heater portion. Accordingly, heat is transmitted directly from a heater portion including a plurality of heat radiating plates and PTC devices, and thus fuel is rapidly heated and a fuel transfer velocity is increased so as to improve engine starting performance at low temperature, thereby improving marketability and convenience.
