[0002] The fuel in the car's fuel tank needs to be pumped by a fuel pump to supply the fuel to the engine at a certain pressure. Generally, there is a fuel pump design in the fuel tank. The risk brought by a single fuel pump is that once the fuel pump is damaged, the fuel supply will be cut off and the engine cannot start. Fuel pumps are mass-produced commodities, and poor quality is inevitable. Especially in some high-end or special models, when completing special working conditions, it is decided to ensure the engine fuel supply. The design of a single fuel pump does not meet the safety requirements for the use of these vehicles. Utility Model Content
