Methods of cleaning fuel pumps are necessary for satisfactory performance and a long life for the pump. Over time, fuel pumps can become contaminated with dirt, rust, and debris, which can lead to inefficiency and eventual failure of the pump. Among the most common ways of cleaning a fuel pump is with fuel system cleaners, which are chemical additives that dissolve various deposits in the fuel lines. These typically contain solvents and detergents that facilitate the breakdown of buildup to improve the working of the fuel pump. These cleaners are generally available and can be used regularly, after every 3,000 to 5,000 miles, to keep the fuel system clean.
Another effective method is by removing the fuel pump and then cleaning it manually. It is done by dismantling the pump and, with the use of a soft-bristled brush and non-abrasive cleaning solutions, lightly scrub its internal components. This is taken to recommend by mechanics, especially in those pumps that have deputed for over 100,000 miles, because deposits may harden more. It should be installed with much care to center it, without which serious damage might occur to sensitive parts like the impeller or the seals, which could blow into more serious problems later on.
Another common practice is fuel system flushing, which is very frequent in those vehicles that have chronic problems in fuel delivery. This procedure runs a solution specially made to clean the fuel lines and pump by running it through them to get rid of contaminants that have built up. Fuel system flushes can indeed clear blockages and smoothen fuel flow. A fuel system flush every 30,000 miles will prevent long-term damage and keep the fuel pump effective.
Sometimes, ultrasonic cleaning can be used to clean the fuel pump. Ultrasonic cleaning is a procedure that uses high-frequency sound waves in a solution to help create minute bubbles that implode to carry away contamination on the surface of the fuel pump. The practice is very effective for cleaning pumps thoroughly without disassembly and is many times used in professional automotive shops.
