Fuel pump assembly

The present disclosure discloses a fuel pump assembly, including a flange, a pressure regulator, an ejector pump assembly, a pump core, a coarse filter, a fuel reservoir, a level sensor, several corrugated hoses, and suction pipes. The pump core has two outlet conduits, one connected to the flange, and the other connected to the ejector pump assembly. The pressure regulator is installed in the flange; when the pressure in the fuel passage is too high, the fuel flows into the fuel reservoir through the pressure regulator. The ejector pump assembly has at least two suction pipes. The ends of the at least two suction pipes are respectively located at the bottoms of the front and rear ends of the fuel tank. This arrangement can significantly improve the stability of fuel supply when driving on long slopes, thus increasing the vehicle's driving range.
