The best way to keep the fuel pump from getting contaminated by rust? One issue with cars, especially ones that were left out in the rain or have been sitting unused for long periods, is rust contamination in the fuel system. Electrolysis due to rust is one of the leading causes of fuel pump failures and accounts for 30% of all fuel system-related issues, according to the National Highway Traffic Safety Administration (NHTSA). Water and oxygen cause rust on the metal parts of the fuel system, and the corrosion is done to the fuel pump, fuel lines, and tank.
Prevent rust contamination with fuel additives that reduce moisture build up. These additives, which generally include water-binding chemicals, can help stop rusting in the fuel system. In high humidity areas, many experts recommend treating fuel with moisture-adsorbing fuel additives every few months. Some things like add a stabilizer that can prevent up to 90% of the water from accumulating in the fuel tank. This aids in the maintenance of clean fuel lines and the prevention of rust inside the pump.
To prevent condensation that can cause rust in the fuel tank, always keep the tank at least one-quarter full. The American Petroleum Institute (API) conducted a study and found out that condensation usually happens when there is an extreme temperature difference from day to night which will lead to moisture inside the tank. The chances of moisture accumulation are reduced when you keep your gas tank full and the Fuel Pump’s lifespan is extended.
Also, replacing the fuel filter regularly can do wonders for preventing rust. A blocked-up filter can hold sediment and moisture, leading to rustification of the fuel pump. Depending on the car’s use and the quality of the fuel, the filter should be changed every 20,000 to 30,000 miles. According to research from the Society of Automotive Engineers (SAE), routine fuel filter maintenance can reduce the risk of rust buildup in the fuel system as much as 25%.
One other important step is to check the fuel tank and to clean it. Dirty, rusty, or dusty tanks also require deep cleaning. If allowed to accumulate, these contaminants will block off the fuel pump and decrease its efficiency. To avoid this, you should take the tank off, then clean it out with specialized rust-removing chemicals doing that will also help ensure the fuel system will stay rust free as well.
A high-quality fuel pump that is made of rust-resistant materials like stainless steel or coated metals will greatly reduce the risk of rust formation as well. A new report from the Automotive Aftermarket Suppliers Association (AASA) found that replacing a standard fuel pump with a version made from corrosion-resistant materials can double its lifespan, stretching it up to 50% longer.
“The best way to prevent fuel pump death from rust is preventive maintenance, which includes additives and keeping your tank full,” Chris Daniels, an automotive repair expert, said. “Over time, the cost savings from fewer repairs and a more reliable pump will far exceed the minor cost associated with preventive measures.”
By taking these precautions, including the use of fuel additives, keeping the proper fuel levels in your vehicle, regularly changing the fuel filter and installing a rust-resistant pump; you can help your fuel pump last significantly longer than usual and prevent the hassle of expensive repairs down the line! If you’re an individual who’s looking for long-term defense of Fuel Pump, a preventative measure is the best plan of action.
