Abstract
A submersible electronic drive module for a vehicle in-tank fuel pump which includes a circuit board assembly having an input connector for receiving a current, an output connector for applying electric power to a fuel pump electric motor, and electrical components for supplying electric power to the motor as a function of vehicle fuel demand. A heat sink of a heat conductive material is thermally connected to the circuit board assembly which absorbs heat generated by the electrical components on the circuit board assembly. Fuel passes through the heat sink to cool it and thus the circuit board assembly and electrical components. A fuel-impervious casing encapsulates the drive module so that fuel is prevented from contacting the circuit board assembly and electrical components. The electronic drive module is removably attached to the fuel pump and is mounted within a fuel tank of an automotive fuel system.
