Claim 6:
7. A fuel pump system for a vehicle, comprising:
a primary fuel pump;
a fuel tank;
an auxiliary fuel pump in-line with the primary fuel pump and fluidly connected to the fuel tank;
an electronic control circuit;
a pressure sensor configured to measure an output pressure from the auxiliary fuel pump and to transmit a signal corresponding to the output pressure to the electronic control circuit;
an electric motor configured to drive the auxiliary fuel pump at an operational motor speed, wherein the electric motor is electrically connected to the electronic control circuit; and
wherein the electronic control circuit is configured to continuously adjust the operational motor speed based on the signal from the pressure sensor to maintain a predetermined constant output pressure; and
a control panel switch having a plurality of modes of operation manually selectable by an operator of the vehicle, wherein one of the modes of operation selectable via the control panel switch is a high boost mode, wherein the high boost mode is set to a fixed voltage corresponding to a predetermined safe speed, and wherein the control panel switch in the high boost mode is electrically connected to the electric motor and bypasses the electronic control circuit.
