How do I change the fuel filter on 93 Buick LeSabre?

To change the fuel filter on a 1993 Buick LeSabre, first, relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Then, 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 using appropriate tools, replace the old filter with a new one, and reconnect the lines, ensuring they are secure. Finally, replace the fuel pump fuse, turn the ignition to the "on" position to prime the system, and check for leaks before starting the engine.
