How Do You Clean a Fuel Pump to Improve Performance?

More importantly, cleaning a fuel pump is very vital, as it helps restore its ability to pump the fuel and remove any unevenness that causes inefficiency in the unit. Dirty fuel injectors and clogged pumps mean a decrease in fuel efficiency of 10-15%, Automotive Maintenance Reports has stated. To solve these problems, start by disconnecting the vehicle’s battery to avoid any electrical shorts, and find the fuel pump (usually in the fuel tank or along the fuel line).

One of the main reasons that cause wear and tear on fuel pumps is the presence of small particles – like rust or dirt – in the fuel system, which disrupts fuel flow. In fact, research shows 30 percent of fuel system failures can be traced to contamination, which highlights the need for routine cleaning. Fuel System Cleaner — Use a fuel system cleaner specifically designed for fuel pumps, such as the Bosch Fuel Injector Cleaner, to help break down these undesirable contaminants. These cleaners are designed to eliminate carbon deposits and carbon impurities in the fuel pump and injectors and improve overall engine performance.

As MotorWeek senior technician John Davis is fond of reminding us, “A little routine cleaning keeps your fuel system in check and saves you the cost and consequences of a fix later.” Ideally, you can also flush the tank with a cleaning solution through the fuel pump and let the liquid run through the system for 10-15 minutes. This process purges the pump’s internal parts and can help clear the filter, which, however, should be replaced if damaged or excessively dirty. A pump with a clogged filter can lose up to 20 percent in efficiency from simply having to work harder to pump the same amount of water.

Moreover, changing fuel filter is part of this.# Most fuel delivery problems can be avoided by replacing a fuel filter every 30,000 miles, according to industry standards. Even the best fuel pump will never give its best performance if the filter is clogged. A dirty filter causes the pump to work at abnormal pressure, which on average on most vehicles will be in between 40-70 PSI.

For cleaning the fuel pump, you should always test it after cleaning. “It will take pressure gauges to check the fuel pump if it is under manufacturer specs or not.” A reading too low or too high indicates cleaning not enough, or pump-down, respectively.

If you have a car that fueld with Ethanol-based fuels, cleaning the fuel pump is more important than ever. Ethanol attracts water and contaminants, which eventually damage the fuel system. According to a study published by the Environmental Protection Agency (EPA), ethanol in fuel causes 15% more corrosion to your vehicle’s fuel system compared to gasoline, requiring regular cleaning for long-lasting performance.

It also includes monitoring the fuel pump’s voltage and current output. A healthy fuel pump will draw a steady current – somewhere in the range of 5-10 amps, depending on the particular specs of your vehicle. A decrease or variation in current may suggest a problem with pump or pump wiring.
