On the 2004 Chevrolet Silverado with a 6.0L Vortec engine, the fuel pressure regulator is integrated into the fuel pump assembly, which is located inside the fuel tank. To access it, you'll typically need to remove the fuel tank, as the regulator is not externally accessible. It's important to relieve fuel system pressure before attempting to service it.
