for Part Number 5022 Fuel Pressure Regulator for Carburetors (7-15 PSI)
with Boost Reference

Lightweight Ceramic Valve, Hard Anodized Billet, .250” Orifice

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

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

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.
