How Long Does a Fuel Pump Last?

[OWyatt]

The fuel pump does not need to be replaced as long as it is not damaged. More information about the lifespan of a fuel pump is as follows: 1. The function of the fuel pump is to draw gasoline from the fuel tank and press it through the pipeline and fuel filter into the float chamber of the carburetor: After two or three years of use, the fuel pump's ability to pump oil may decline due to wear and tear, and whether it needs to be replaced should be determined after corresponding tests by technicians. 2. The fuel pump should be replaced promptly if it fails: When the fuel pump has a pressure relief failure, it will cause a "buzzing" abnormal noise under the rear seat when the vehicle is running; the vehicle will have weak acceleration, especially with a jerky feeling during sudden acceleration; difficulty starting the vehicle or failure to start; the engine fault light on the vehicle's combination instrument panel stays on. If these phenomena occur, the fuel pump should be replaced promptly.
