Lightweight Ceramic Valve, Hard Anodized Billet250" Orifice For Smoother Fuel Pressure at Lower Demand
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 -8 AN O-ring, these are outlet ports to the fuel rails. You may use just one or both of these ports.
The -4 idle bleed must be returned to the fuel cell.
The #40 jet in the idle bleed will reduce idle pressure by 10-20 pounds.
The 1/8” barbed fitting is a vent. Install a short piece of vacuum hose to a clean/dry area.
The socket head set screw on the top of the regulator adjusts the fuel pressure. Screwing it in increases fuel pressure, out decreases fuel pressure.
