Where is the fuel regulator on a 1999 Chevrolet Silverado 2500?
The fuel pressure regulator on a 1999 Chevrolet Silverado 2500 is integrated into the fuel rail. It's not a separate, easily identifiable component like on some older vehicles. You'll find the fuel rail on the top of the engine, near the intake manifold. The regulator itself is part of the fuel rail assembly.
