Abstract
A fuel pump controller includes a detecting device for detecting environmental vibrational energy and converting the environmental vibrational energy into an electrical signal. A motor controller is coupled to a fuel pump motor wherein the electrical signal is used by the controller to command the fuel pump motor to operate at one of a plurality of speeds wherein the commanded speed is at least in part a function of the environmental vibrational energy.
