What You'll Learn
Fuel filters should be replaced every 20,000 miles or so
If your car has been sitting unused with gas in the tank for more than 3 to 6 months, it is recommended that you drain the gas and replace the fuel filter. This is because gasoline is perishable and will eventually degrade into compounds that can damage the fuel system.
Changing the fuel filter is usually a straightforward process and does not require a diagnosis. It is often replaced as part of scheduled maintenance or as a repair if there is an issue with the fuel system. If you are unsure about how to change the fuel filter yourself, it is best to take it to a mechanic or a dealer to get it done.

Fuel filters should be replaced if the car has been unused for 3-6 months
Fuel filters are most often replaced as scheduled maintenance, or as part of a repair necessitating early replacement of the fuel filter. If the fuel system is being diagnosed, the fuel filter may be replaced as a step in the diagnosis. If the fuel filter has been run past the replacement interval, or if it was noted that the fuel tank had contaminants in it, the filter will immediately be suspected of failure in the case of any fueling issue.
The fuel sending unit, pump, and filter are all one assembly. The fuel pick-up is mounted to the bottom of the fuel pump and looks like a sock. It keeps larger debris from entering the fuel pump and damaging it. The actual fuel filter is usually located further downstream after the fuel pump to filtrate smaller debris from entering the fuel injectors.
It is recommended to change the fuel filter about every 20,000 miles, or 4,000 miles if the car has performance parts.
