How do you replace the fuel filter in 1997 Mazda 323?

To replace the fuel filter in a 1997 Mazda 323, first, ensure the vehicle is off and relieve the fuel pressure by removing the fuel pump fuse and running the engine until it stalls. Locate the fuel filter, which is typically found along the fuel line near the rear of the vehicle. Disconnect the fuel lines from the filter, taking care to catch any spilled fuel, and remove the filter from its mounting bracket. Install the new filter in the same orientation, reconnect the fuel lines, and replace the fuel pump fuse before starting the engine to check for leaks.
