A fuel delivery system for an internal combustion engine that includes a fuel supply, an electric motor pump for feeding fuel under pressure from the supply to the engine, a pressure sensitive switch operatively coupled to the pump and having a first contact movably responsive to fuel pressure and a second contact opposed to said first contact, and a PWM amplifier responsive to the pressure sensitive switch for applying electrical power to said pump. The second switch contact is mounted on a bimetallic spring responsive to fuel temperature for altering operating characteristics of the switch, and thereby altering fuel pressure characteristics of said system as a function of fuel temperature.
