Abstract: A fuel feed system for an automotive type internal combustion engine has a fuel reservoir from which fuel normally is supplied at a constant volume to the inlet side of a high pressure pump from a low pressure supply pump located in a fuel tank; the reservoir contains valving that automatically redirects fuel, which normally is returned from the high pressure pump directly to the fuel tank, back into the reservoir to maintain the constant supply of fuel to the inlet side of the high pressure pump even though the normal supply line is exposed to air and therefore not supplying fuel to the reservoir, thus preventing fuel starvation of the high pressure pump during the momentary exposure of its fuel supply line to air.
