★ Top Answer
On the Mazda3, you can find the fuel pressure regulator at the end of the fuel rail that is connected to the injectors. This component regulates the fuel pressure that moves through the engine. If you notice black smoke coming from your car’s tailpipe, it likely indicates a problem with the fuel pressure regulator. When you see black smoke, it’s important to have the regulator inspected or changed promptly. Typically, when smoke is visible from your tailpipe, it should be white or gray; black smoke is a clear sign of trouble.
