How do you change the fuel filter on a 2001 Porsche 911?

To change the fuel filter on a 2001 Porsche 911, first ensure the engine is off and the vehicle is cool. Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls. Next, locate the fuel filter, typically found near the fuel tank or along the chassis. Disconnect the fuel lines, remove the old filter, and install the new one, ensuring the flow direction matches the markings, then reconnect the fuel lines and reinsert the fuse.
