Replacing the fuel pump is a relatively common repair, especially on higher-mileage vehicles. Most in-tank fuel pumps are life-spanned at around 100,000 to 150,000 miles, but the life of the pump may vary given the quality of fuel, driving habits, and routine maintenance practices. In modern vehicles, the Fuel Pump is generally fitted inside the fuel tank and always works to provide fuel at the required pressure, which is usually in the range of 40 to 60 psi for fuel-injected engines. Because it has to constantly work under such demand, it could be subjected to wear and tear and may need replacement after a certain period, especially when it operates under strain due to low fuel levels or clogged filters.
Fuel contamination is one of the most common issues that lead to the failure of the pump. Such contamination occurs when debris or sediment enters the fuel tank. Contamination clogs the fuel filter, which puts pressure on the pump to force the fuel harder. This can cause the pump to overheat and wear out faster with time. Changing fuel filters regularly, usually every 30,000 miles, reduces the possibility of pump failure by preventing any contaminants from entering the fuel system.
These symptoms may cause the vehicle to buck or hesitate, demonstrate poor cold or hot starting, misfire, or lose power under load, any of which can indicate the need for replacement of the fuel pump. The National Highway Traffic Safety Administration also says that most breakdowns occur because of problems with the fuel system, again indicating the importance of a properly functioning fuel pump in ensuring reliability. If these symptoms appear, drivers should take action immediately, since the longer they wait, the more damage there will be, adding up to the cost of repair. On average, replacing the pump usually costs between $400 and $800.
As Carroll Shelby once said, “Performance and reliability do not happen by accident.” A quality fuel pump investment added to one’s regular maintenance routine promises reliability with less frequency of repairs. Replacing fuel pumps remains a very common yet essential repair in higher mileage vehicles just to ensure that your engine keeps running well and doesn’t break down unexpectedly.
