Patent 7314040 was granted and assigned to Denso on January, 2008 by the United States Patent and Trademark Office.
In a fuel supply apparatus, a circuit module has a housing, a driving circuit contained in the housing, an electric connector. The circuit module is mounted to a cover member that is disposed to close an opening of a fuel tank. A fuel pump is supported by the cover member in the inside of the fuel tank and receives a driving current from the driving circuit. In the circuit module, the electric connector is integrated with the housing. Accordingly, an external size of the circuit module is reduced.
