How do you remove a fuel pressure regulator on a 1997 Hyundai Accent?

To remove the fuel pressure regulator on a 1997 Hyundai Accent, first, relieve the fuel system pressure by disconnecting the fuel pump fuse and running the engine until it stalls. Once the pressure is relieved, disconnect the fuel lines from the regulator and remove any mounting bolts. Carefully pull the regulator off the fuel rail, ensuring any O-rings are removed as well. Replace with the new regulator, reattach the fuel lines, and restore the fuel pump fuse.
