Where and how do you change the fuel filter in a 2004 Buick Rendezvous?

To change the fuel filter in a 2004 Buick Rendezvous, first, locate the filter, which is typically found along the frame rail on the driver's side. Begin by relieving the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Once the pressure is released, disconnect the fuel lines from the filter using a fuel line disconnect tool, replace the old filter with a new one, and reconnect the lines. Finally, reinstall the fuel pump relay and start the engine to check for leaks.
