Abstract
In order to solve a problem that, under the condition that an amount of the residual fuel within a fuel reservoir is small, the fuel within the fuel reservoir is biased by a swing motion of the fuel caused by an abrupt acceleration or an abrupt braking of an automotive vehicle so that the amount of the fuel in the vicinity of a suction port of the fuel pump is deficient and a sufficient amount of fuel may not be supplied to an engine, an outlet port of a return piping for returning into the fuel reservoir extra fuel from a pressure regulator, out of the fuel to be fed under pressure through the pressure regulator from an interior of the fuel reservoir by the fuel pump is disposed within a sub-tank, and the extra fuel is directed and close to the suction port of the fuel pump.
