Abstract: The disclosed lift pump employs a unique arrangement of conductive studs to transmit the three phases of motor power from the control board to the brushless motor. The conductive studs penetrate the wall of the motor/pump enclosure, which is otherwise non-conductive. The conductive studs are intentionally larger than needed to transmit the current used by the motor, and are arranged in thermal contact with heat conductive portions of the motor control board to transmit heat from the control board into the motor/pump enclosure where heat is transmitted to fuel passing through the assembly. An additional center heat sink is situated in a position aligned with heat generating capacitors that are part of the motor drive circuitry on the motor control board.

Abstract: A fuel-supply system has a fuel pump, a pressure controller, a signal output device and a power switch. The pressure controller adjusts the observed fuel pressure of the fuel and may electronically communicate with a motor driving the fuel pump to regulate the supply of fuel from a fuel tank of the fuel-supply system to an engine. In detail, the pressure controller performs feedback control of a voltage applied to the motor such that the pressure of a fuel pumped from the fuel pump approaches to have a first target and/or ideal fuel pressure value. Further, the signal output device outputs the first target fuel pressure value to the pressure controller. Activation of the power switch supplies power, from a power source, to the pressure controller, the motor and the signal output device. Further, the pressure controller may perform feedback control based on a second target fuel pressure value.
