ABSTRACT:
A fuel delivery system for an internal combustion engine that includes a fuel pump responsive to application of electrical power for delivering fuel under pressure to the engine. A pressure sensor supplies a pressure signal as a function of fuel pump output pressure. Electrical circuitry is responsive to the pressure signal for applying electrical power to the pump. A temperature sensor is operatively coupled to the circuitry for automatically varying the pump power signal to increase fuel pump output pressure when temperature at the temperature sensor exceeds preselected threshold temperature.
