Where is the fuel pressure regulator on a 1995 Chevy blazer?

On a 1995 Chevy Blazer, the fuel pressure regulator is integrated into the fuel rail. It's not a separate, easily identifiable component like on some older vehicles. You'll find it on the fuel rail itself, usually near one of the fuel injectors. You'll likely need to access it from above, possibly requiring removal of some engine bay components for better visibility and access.
