[0002] The existing fuel supply system for an engine with a fuel tank usually connects the fuel tank, fuel pump, pressure regulator and some pipelines together to form a system that can supply fuel to the engine, wherein the pressure regulator and the fuel tank The design of the fuel delivery system used in combination with the fuel pump is relatively complicated. Not only the pressure regulator itself must be installed on the engine, but also an additional pipeline returning to the fuel tank must be provided, and an additional return hole needs to be opened on the fuel tank to communicate with the return Pipeline docking of the fuel tank, this system is not only complex in structure, narrow in scope of use, and poor in applicability, but also this modification method of opening an additional return hole on the fuel tank will also reduce the service life and reliability of the fuel tank
