Abstract
A method and an apparatus for operating a fuel supply system, in particular a fuel injection system, in which a fuel supply pump continuously supplies fuel and wherein the excess fuel not required for injection is returned to the fuel reservoir. In order to reduce the average operating power of the pump and thus reduce the average amount of fuel returned to the tank, thereby reducing undesirable temperature increases of the fuel in the reservoir, the system fuel pressure is monitored and maintained at a value substantially equal to a reference value. The electrical power of the fuel supply pump is altered continuously so as to maintain the fuel system pressure at the reference level.
