A fuel filter is a device that removes contaminants from fuel before it enters the engine. Fuel filters should be replaced according to the manufacturer's recommendations, which typically range from 15,000 to 30,000 miles. However, there are some signs that may indicate that a fuel filter needs to be replaced sooner, such as:
* Decreased fuel efficiency
* Engine hesitation or stalling
* Rough idling
* Hard starting
* Check engine light illumination
If you experience any of these symptoms, it is important to have your fuel filter inspected and replaced if necessary.
