How Many Years Can a Fuel Pump Last?
2 Answers
Fuel pumps can last for 5 years. Depending on the driving method, they can be divided into mechanically driven diaphragm type and electrically driven type. The functions of a fuel pump: 1. Draw fuel from the fuel tank, pressurize it, and deliver it to the fuel supply pipe, working with the fuel pressure regulator to establish fuel pressure; 2. Deliver high-pressure fuel to the fuel distribution pipe, ensuring a continuous supply of fuel to the fuel injectors. Safety precautions for fuel pump fault detection: 1. When troubleshooting a fuel pump that has been used for a long time, do not perform a dry test to avoid sparks caused by poor contact between the brush and the commutator, which could ignite the fuel inside the pump casing and cause an explosion; 2. After removing the fuel pump from the fuel tank, clean it promptly to avoid generating sparks.
When I drove a taxi, the durability of the fuel pump depended entirely on how you used and maintained the vehicle. Generally, it could last 8 to 10 years without issues, but this is more closely related to mileage. If you frequently drive in the city, encountering traffic jams or making short trips with frequent stops and starts, the engine keeps running, causing the pump to draw fuel more frequently. This can lead to overheating and a shorter lifespan, potentially causing problems in just 5 to 7 years. On the other hand, long highway trips can extend its durability for many years. In terms of maintenance, the most critical thing is not to always wait until the fuel is almost empty before refilling. Low fuel levels can cause the pump to overheat and burn out internal components. Additionally, the fuel filter must be replaced regularly; otherwise, clogging from impurities can cause the pump to underperform or fail completely. My first car’s pump lasted until 150,000 kilometers, but the second one failed after just 6 years—all because I neglected to change the filter and used cheap fuel. Fuel quality also plays a significant role; using high-quality gasoline from reputable gas stations reduces the risk of corrosion. Regular maintenance checks on the fuel pressure system can help you detect potential issues early, avoiding breakdowns on the road.
