The oil leakage of the fuel pump may be caused by the aging of the pipe. It is recommended to replace it as soon as possible:
1. Fuel pump is a professional term in the auto parts industry. It is one of the basic components of the fuel injection system of electronic fuel injection vehicles. It is located inside the fuel tank of the vehicle. The fuel pump works when it is started and the engine is running;
2. If the engine is stopped and the ignition switch is still ON, the HFMSFI control module turns off the power of the fuel pump to avoid accidental ignition;
3. The function of the fuel pump is to suck out the fuel from the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure.

1. The failure rate of the automobile oil pump is higher than that of other electrical appliances. It is usually replaced after the fault is judged, and there is no certain replacement cycle;
2. If you say it must be replaced, most of them refer to the replacement of the gasoline filter built into the fuel tank, which can be replaced at 40,000 kilometers, but in fact the original intention of the design is maintenance-free, because the quality of domestic oil products is unstable, so maintenance is required;
3. When the filter is disassembled, it is easy to cause damage to the oil pump, which creates the illusion that the oil pump is easily broken. It is recommended to go to a regular manufacturer for maintenance, which can cause unnecessary expenses due to avoided technical reasons.
