How often should the fuel pump be replaced?
1 Answers
Fuel pumps generally need to be replaced around 100,000 kilometers. Here are the specific details about automotive high-pressure fuel pumps: 1. Function: The fuel pump serves as the interface between the high-pressure and low-pressure fuel circuits, controlling the fuel output to generate fuel pressure in the common rail. Its role is to increase fuel pressure for high-pressure injection to achieve atomization. 2. Purpose: The primary use of fuel pumps is as a power source for hydraulic devices such as jacks, header machines, extruders, and cotton gins. 3. Installation precautions: During the installation of the fuel pump, all openings should be covered to prevent foreign objects from entering the machine.
