Lightweight Ceramic Valve, Hard Anodized Billet, Large Orifice

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

The lower port is -8 AN O-ring, this is the inlet from the fuel pump.

The side ports are -6 AN O-ring, these are outlet ports to the fuel rails. 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.
