How often should the car's fuel filter be replaced?
2 Answers
The car's fuel filter should be replaced approximately every 60,000 kilometers. The replacement method is as follows: 1. Release the residual pressure in the fuel system; 2. Remove the grounding wire near the fuel filter; 3. Place a container under the filter; 4. Pull out the fuel inlet pipe and then remove the adjacent fuel outlet pipe; 5. Remove the old fuel filter to complete the replacement. Precautions for replacing the fuel filter include: 1. Ensure the overall sealing of the air filter and cabin air filter; 2. Use the gasoline grade specified by the car manufacturer. The fuel filter, also known as the fuel strainer, functions to remove iron oxide, dust, and solid impurities contained in the fuel, preventing fuel system blockages, reducing mechanical wear, ensuring stable engine operation, and improving reliability.
Last time my friend's SUV broke down on the road because the fuel filter wasn't replaced in time, costing over 800 yuan for towing. Generally speaking, the fuel filter should be replaced every 20,000 to 40,000 kilometers, depending on your vehicle's manual requirements. Experienced drivers know that impurities inevitably settle in the fuel tank. This filter acts like a water purifier for the fuel system. If it gets clogged and restricts fuel flow, the mildest consequence is sluggish acceleration, while the worst-case scenario could lead to complete failure of the fuel injectors. For those of us in northern regions using ethanol-blended gasoline during winter, more frequent checks are necessary, especially since fuel quality varies significantly between gas stations, causing the filter to clog up faster. Honestly, replacing a fuel filter doesn't cost much—don't wait until the warning light comes on to think about it.
