You need to proactively protect the whole fuel delivery system from getting damaged by any scale of contaminants. Contaminants, including dirt, rust, and water, can get into the fuel tank while being refueled or through degenerated fuel over time. Research has shown that 80% of premature Fuel Pump failures are attributed to contamination and prevention is the only way to ensure pump life.
Quality fuel prevents contamination — and is your number one line of defense Higher-priced fuels oftentimes have detergents in them that assist with keeping the fuel system clean. Top Tier Gasoline is certified by the American Petroleum Institute (API) to minimize harmful deposits by up to 50%. By consistently driving on certified fuels, the chances of contaminants getting to the pump is reduced.
Changing a fuel filter regularly is also very important. Fuel filters are used to catch all the dirt and crud that might flow before it gets into the pump. In-time these filters get clogged and result in a reduced amount of fuel flow while the pump is higher-effort. Fuel filter Automotive specialists recommend a new fuel filter every 20,000 to 30,000 miles or as directed in your vehicle owner manual. If you don’t maintain it, the efficiency of your fuel system can decrease by 15-20%.
By maintaining the fuel tank at least 25% full, you prevent water and sediment from being sucked into the pump. Fuel is a natural coolant and lubricant for the pump, and low fuel levels allow more opportunity for debris to enter the system. AAA says that allowing it to run near empty raises the temperature of the pump and shortens its life, so keeping a fuller tank is better.
The larger risk of contamination also is minimized by only refueling at well-known filling stations. At turnover stations there is less chance that old water or sediment has found its way to the tank. According to a study from 2022, independent stations were observed with no proper maintenance and upticks at levels three times higher in many cases than what is found at major brand locations. Protection starts at the source with clean fuel but it does end there.
Periodic cleaning of the fuel system will also help eliminate impurities that escape the trap. Cleaning additives break down deposits in the tank, lines and injectors. According to Bosch, a leader in fuel system technology, regular cleanings will increase the overall performance of your vehicle and diminish premature pump wear.
As long as the fuel delivery system is not contaminated, proper maintenance and vigilance can keep it that way. Using higher-quality fuel, changing your filter regularly and getting your Fuel Pump serviced can lower the likelihood of any damage occurring while also prolonging the life span. Not to mention these preventive actions not only turn out to be saving because you have less repairs but they also keep the car going great regularly.
