How many kilometers can a fuel pump generally last?

[EdwardAnn]

The service life of a fuel pump is approximately 100,000 kilometers. In practical use, it is advisable to replace it upon failure. As a fundamental component of the engine's fuel supply system, the fuel pump is responsible for drawing fuel from the tank during engine operation, delivering it at a certain pressure through the fuel supply line to the engine, where it undergoes secondary pressurization by the high-pressure fuel pump. It then supplies a measured amount of fuel to each cylinder according to the engine's firing order. Symptoms of a failing fuel pump include: 1. Weak acceleration with jerking during sudden acceleration; 2. Difficulty starting, requiring prolonged ignition; 3. Illuminated engine warning light; 4. Unusual noises during driving; 5. Abnormal engine vibration; 6. Failure of the fuel supply system.
