What are the symptoms of a dirty fuel filter?

The symptoms of a dirty fuel filter include: reduced engine efficiency, increased carbon deposits, damage to the cylinder and surrounding components, poor fuel supply, insufficient vehicle power, and even stalling. A dirty fuel filter increases the likelihood of impurities entering the engine. If these impurities are not filtered out, over time, the fuel lines and fuel injection system can also become corroded and damaged. The fuel filter is connected to the fuel pump. If there are too many impurities in the fuel, they can clog the fuel injectors, leading to poor fuel supply. A clogged fuel filter can affect the amount of fuel entering the engine, and insufficient fuel intake can make the engine difficult to start. Most filters use a paper filter element enclosed in a hard plastic shell, allowing the internal fuel level to be observed from the outside. Therefore, by observing the rise in the fuel level, one can determine whether the filter is clogged.
Last time I drove out, I suddenly found my beloved car was extremely hard to start, as if the engine was gasping for breath. When I stepped on the accelerator, it felt powerless, crawling slowly even up a small slope, and the fuel consumption inexplicably increased a lot, literally burning money. When idling, the car body kept shaking intermittently, occasionally stalling, which scared me thinking it might break down halfway. These symptoms likely indicate a dirty or clogged fuel filter, affecting the smooth flow of fuel and consequently dragging the engine down. It's necessary to go to the garage immediately to replace the filter to prevent a minor issue from turning into a major repair.
