To change the fuel filter built into the fuel tank of a 2003 Mazda 323, first, ensure the vehicle is turned off and the battery is disconnected. Remove the fuel tank by draining it and disconnecting the fuel lines and brackets. Once the tank is out, access the fuel pump assembly where the filter is located, and replace the old filter with a new one. Reassemble the tank and reconnect all lines before starting the vehicle.
