Changing the fuel pump filter at home will remarkably enhance the performance of your vehicle. Some of the common issues that might be developed by the clogged fuel pump filter are poor fuel pressure, engine misfires, or stalling. According to the Automotive Maintenance Guide of Consumer Reports, “clogged fuel filters are responsible for nearly 15-20 percent of fuel-related engine problems.”. If you happen to experience poorer fuel economy or performance from your engine, be sure to clean out the blockage in your fuel filter first. The first thing to do is locate the fuel pump filter within your vehicle. In most automobiles, the filter is situated along the fuel line between the Fuel Pump and the engine; usually, underneath the car or within the fuel tank itself. The National Automotive Service Excellence, ASE, recommends the use of a fuel pressure gauge to ascertain if the fuel pressure is less than the recommended by the manufacturer, hence the filter has clogged. For example, if the fuel pressure reading is 5-10 psi lower than usual, this may mean that the filter is clogged.
After locating the filter, relieve the fuel system pressure so that fuel does not spray all over when the filter is removed. This can be done by locating the fuel pressure relief valve and using a wrench to relieve the pressure. According to AutoZone, protective gloves and goggles should be worn at this stage to prevent injury from gasoline exposure. Remove the fuel filter with a wrench or by loosening the screws holding it in place. The process might just be a little different with your car model.
Next, inspect the filter for any dirt, debris, or rust accumulation. If it’s clogged but still in good condition, it coul
d be cleaned using fuel system cleaner, which is usually available at most auto parts stores. Pour the cleaner through the filter while slightly tapping it with a mallet to dislodge the debris. The Fuel Injector Cleaner can be used, according to Edelbrock, to flush the filter for about 10 minutes. Otherwise, it needs replacement with a new one in cases where the filter is extremely clogged or completely destroyed. Filters cost on average anything between $10 and $30 according to the type and make of the vehicle.
Once cleaned or replaced, reattach the filter, ensuring it is securely tightened. Reconnect the fuel lines and check for any leaks. DIY mechanics often report that improperly reattaching fuel lines can lead to fuel leakage, which can be dangerous. After reinstallation, start the engine to verify the fix. If the car runs smoothly without stalling or sputtering, the clogged filter has been successfully addressed.
After replacing or cleaning the fuel filter, the Fuel Pump itself may also need to be checked, since a clogged filter can strain the pump and possibly cause further damage. A clean filter ensures that the fuel pump operates at maximum efficiency to help prolong its life and maintain the vehicle’s fuel economy.
By fixing a clogged Fuel Pump filter at home, you can save $100 or more in repair costs that would otherwise be spent at a garage. However, if you are not comfortable with the process or do not have the right tools, it is best to seek professional help so that the repair is done properly.
