* Reduced engine power: When the fuel filter is clogged, the engine doesn't get the fuel it needs to operate at full power. This can cause the engine to hesitate or stall, especially under load.
* Rough idling: A clogged fuel filter can also cause the engine to idle rough. This is because the fuel flow to the engine is inconsistent, which can cause the engine to surge or stall.
* Stalling: A clogged fuel filter can cause the engine to stall, especially when the vehicle is idling or under load. This is because the fuel flow to the engine is cut off completely, which causes the engine to stop running.
* Engine damage: If the fuel filter becomes clogged, it can damage the engine. This is because the dirt and contaminants that accumulate in the filter can damage the fuel injectors and other engine components.
In addition to these problems, a clogged fuel filter can also lead to increased fuel consumption and emissions. If you suspect that your fuel filter is clogged, it is important to have it replaced as soon as possible.
