The Race Pumps fuel pressure regulator installs between the fuel pump and the carburetor.

The side ports are -8 AN O-ring, these are outlet ports to the carburetor. You may use just one or both of these ports.

The -3 port for the boost reference is also the pressure adjuster. Screwing it in increases fuel pressure, out decreases fuel pressure. Most carburetors work well with 7 PSI on gasoline and 9 PSI on methanol.
