In the case of a fuel supply device that utilizes a conventional brushless fuel pump and a capacitive fuel level gauge, control units are separately provided, and because each control unit has only one of two functions, the overall configuration becomes complicated. In addition, there is a problem that because the capacitive fuel level gauge is susceptible to a stray capacitance due to the principle thereof, the S/N ratio is deteriorated as affected by non-uniform wiring during production and vibrations of wiring during use. By integrating the control unit for the brushless fuel pump (100) with the control unit for the capacitive fuel level gauge (110) and installing the resulting control unit (120) on the top surface (flange section) (103) of the fuel pump, both of the functions can be implemented with a simple configuration, and the fuel supply device can be made small. |
