Disclosed is an emergency bypass mechanism to route fuel around an electronically controlled fuel flow regulator of a combat vehicle when flow through the regulator becomes severely restricted. The mechanism includes electrically actuated valves hydraulically in parallel with the regulator, the valves being partly controlled by signals generated during manually shifting of the vehicle\s transmission and partly controlled by a system of switches in a control panel.

A system for supplying fuel to the engine of a combat vehicle having a manually operable transmission and a shift lever for shifting gears in the transmission, comprising: a source of fluid fuel; a constant pressure pump hydraulically connected to the source of fluid fuel; electronically controlled means for regulating the flow of fuel from the pump to the engine; a plurality of electrically operated bypass valves hydraulically in parallel with one another and with the regulating means; an electrical power source for energizing the bypass valves; an interrupter switch electrically connected between the power source and the bypass valves; an interrupter coil to open the interrupter switch when the interrupter coil is energized; a lever switch controlled by the transmission lever connected between the power source and the interrupter coil; a master switch electrically connected between the interrupter switch and the bypass valves; a master coil in series with the master switch to magnetically maintain the master switch in its closed position when the master coil is energized; a plurality of manually actuated valve control switches electrically in parallel with one another and in series with the master switch, one of the electrically operated bypass valves being connected in series with a corresponding valve control switch.
