Motor vehicle fuel tank

A motor-vehicle fuel reservoir defining a volume for holding a fuel which is used by an engine comprising:

• a reserve container which is located in the volume and which defines a reserve volume;
• a fuel pump located in said reserve container which pumps a pumped amount of fuel from the fuel located in the reserve volume of the reserve container, which pumped amount is in excess of a required amount of fuel required for delivery to the engine so that there is an excess amount of fuel pumped by the fuel pump;
• a pressure regulator located in the volume and outside of the reserve volume;
• a fuel filter located in the volume and housed in a housing which is outside of the reserve volume of the reserve container, said fuel filter including three discrete tubes, namely
• a filter delivery tube by which the pumped amount of fuel pumped by said fuel pump is delivered directly to the fuel filter for filtering,
• an engine delivery tube by which the required amount of the pumped amount of fuel filtered by the fuel filter is delivered directly to the engine, and
• a regulator delivery tube by which the excess amount of the pumped amount of fuel filtered by the fuel filter is delivered directly to the pressure regulator;
• and
• a suction jet pump which is located in the volume and outside of the reserve volume, and which is operated with the excess amount of fuel coming directly from the pressure regulator and previously from the fuel filter, the suction jet pump
• a) sucking in fuel from at least one low suction point which low suction point is located outside of the reserve container and
• b) delivering the sucked in fuel to the reserve container together with the excess amount of fuel at at least one high delivery point situated above a desired minimum level of fuel in the reserve container and higher than the low suction point.
