How Long Should a Fuel Pump Last?

Generally, a fuel pump may last from 100,000 to 200,000 miles. However, such factors as driving habits, maintenance practices, and fuel quality will affect the life. Proper maintenance can greatly extend life, as in things like changing the fuel filter every 20,000 to 30,000 miles can help. A clean fuel filter reduces strain on the pump by preventing debris from clogging the system. This can increase efficiency as much as 15%.
It is also dependent on driving conditions. Vehicles exposed to stop-and-go traffic or in heavy load conditions, like towing, the pump wears off sooner. High-performance applications require more from a Fuel Pump and thus come out with earlier failures, sometimes within 70,000 miles if precautions aren’t taken accordingly.

Moreover, the quality of the fuel used will also decide the life of the Fuel Pump. Fuels containing a high percentage of ethanol or other contaminants in them can result in corrosion and damage to the components making up the pump. The use of good-quality fuel could help reduce such risks and ensure that the pump serves effectively within its lifetime. Data shows that the usage of cleaner fuels can result in an extension of the pump’s life by as much as 30%, due to minimal deposits that build up to harmful levels.

The symptoms of a failing Fuel Pump are engine sputtering, difficulty starting, and decreased acceleration. In case any of these symptoms show up with your vehicle, one must take immediate action. Lack of response may lead to complete failure of the pump that may require repairs or replacements, depending upon the make and model of the vehicle, which could be very costly. These can range between $100 on the lower side to above $1,000.

The premature failure will be avoided by adopting precautions like routine inspection of the Fuel Pump and its components. Ensuring that the electrical connections are secure and free from corrosion further supports long life to the pump. Proper maintenance of the fuel system and a regular maintenance schedule by the driver will enable the Fuel Pump to function effectively and last as long as possible.
