The best way to maintain a fuel pump in good condition includes regular care for the fuel system itself and habits that keep the pump from unnecessary stress or blockages. Not letting the fuel tank go below a quarter full is highly important, as low levels expose the pump to overheating by reducing the cooling effect provided by surrounding fuel. Consistently low fuel also causes a collection of sediment near the pump intake that can clog the pump and can knock a good 100,000 miles off of its optimal life.
Equally crucial in the maintenance of the fuel pump is the change of the fuel filter at 30,000 miles. In principle, the filter is meant to block dirt, rust, and other forms of debris from passing through it into the pump. In so doing, this helps the pump not overwork in passing fuel through a blocked path. As it clogs up, the flow of fuel reduces and the pump is overworking, hence raising the temperature of operation and general wear. A clean filter necessarily reduces strain to help the pump function efficiently and extend its service life.
Good-quality fuel reduces the possibility of anything inside the tank that is harmful to the pump, either by clogging or even causing damage. Poor fuel quality normally contains impurities that settle at the bottom of the tank, increasing the chances of clogging. Fuel system cleaners added every 10,000 to 15,000 miles help to clean any varnish buildup in the tank and fuel lines, providing further protection to the pump against clogs and strain. The cleaners will also keep fuel flow at optimal levels, supporting efficient engine performance.
The early symptoms of fuel pump failure are picked by monitoring symptoms of difficult starts, sputtering, and other noises emanating from the tank area. This being the case, addressing the signs early with a view to not waiting until complete failure occurs can minimize the repair costs and sudden breakdowns. As Carroll Shelby once said, “The cleaner your machine, the longer it will run,” which goes to say that with due care and maintenance, most parts of an automobile have longer lives. Proper maintenance of the fuel pump includes replacing fuel filters, using high-quality fuel, and maintaining consistent levels to keep your Fuel Pump running smoothly and efficiently for maximum engine performance and fuel efficiency.
