What happens when a car's fuel filter is clogged?

When a car's fuel filter is clogged, the following situations may occur: 1. The car is prone to stalling. After the fuel filter is clogged, the delivery of gasoline is affected, leading to insufficient fuel supply to the engine. This results in noticeable jerking while driving or shifting gears, and the car is highly likely to stall when idling; 2. The car lacks power when driving. Due to poor fuel supply, the engine's power output decreases, causing the vehicle to lack power and reduce speed; 3. The engine shakes when idling. Moderate clogging of the fuel filter not only worsens the car's power but also causes the engine to shake when the car is idling. It is necessary to clean the fuel filter promptly. The filter can be removed for cleaning. If it is a ceramic filter, it can be lit and allowed to burn out, then tapped to remove the ashes and dirt before reinstalling. If it is a paper filter, it can be cleaned in gasoline.
Once my car's fuel filter got clogged, and I didn't notice it at first. But after a few days, starting the engine became difficult, requiring multiple attempts to ignite. While driving, the engine would suddenly shake, and acceleration felt noticeably weak, like stepping on cotton. Later, the car stalled directly at a red light, almost causing a rear-end collision. At the repair shop, the mechanic said the filter was completely blocked by impurities, causing insufficient fuel supply. Fortunately, it was discovered early, and only the filter needed to be replaced. Regular maintenance is essential—don't wait until major problems arise.
