In case you want to salvage a unit off of a junker: 1982 Nissan Turbo units have a Fuel Pump Control Modulator that "monitors engine conditions (engine rpm, cylinder head temp, injector operating pulse width, etc.) and controls the voltage supplied to the fuel pump." The pumps draws battery voltage when: engine cranking, above 3,200 rpm, injector pulse width above 3.5 m sec, cylinder head temp of 100 deg C (212 deg F), battery voltage below 9.8V: other than those conditions it draws 9.8V. The unit can be found just above the ECCS control unit on drivers side, inside car.
