However, avoiding fuel pump problems is possible with the right maintenance in addition to good driving behavior. One of the easiest prevention methods is to keep the fuel tank above a quarter full, as the internal components are cooled and lubricated by the fuel. A lack of fuel can overheat the pump which may lead to a drop of its efficiency by 20-30% and greatly decrease its service life.
Changing the fuel filter regularly can also be an effective way to avoid fuel pump problems. Filters are designed to keep dirt, rust and other particles out of the pump. A clogged filter causes the pump to operate under duress, thus sustaining it incurring premature wear According to experts from the automotive field, a fuel filter replacement every 20 to 30 thousand miles may seem like just another maintenance item; however it is a cheap form of service that could give an extra two to three years of life on the pump.
High-grade fuel also goes long way in minimizing pump issues. Dirty fuel or ethanol levels above 10% can cause more deposits and the system to form sludge, thus obstructing it. One of the most common reasons for pump clogging, say mechanics is running fuel of dubious quality: Another study suggests ethanol contents in excess to 10% can wear pumps up to an extra 15%.
Problems in regard to electricity can be very detrimental to fuel pump life. Similarly, loose connections or poor ground can lead to intermittent pump operation which in turn causes fuel pressure issues. Safe wiring practices and regular checks of connections are all that is needed to prevent electrical woes such as these. According to automotive repair services, a major report suggests that almost 10% of fuel pump failures are due to electrical faults which indicates the increased need for a steady and stable supply of electricity for efficient pumping.
Adding a fuel system cleaner from time to time for high-mileage cars can help melt away small deposits and keep the fuel pump and injectors clean. But keep in mind that this procedure must also be performed with moderation as per the manufacturers recommendation to not put unnecessary wear on the pump.
These inspections will keep the fuel pump functioning properly and will help prevent expensive repairs. Learn more about fuel pumps care and dependable spare parts, check out Fuel Pump.
