Radium DFPR, Dual Fuel Pressure Regulator jza80 supra The Radium Engineering adapter splits

The Radium Engineering adapter splits the fuel flow into an auxiliary passage parallel to the sensor

unlike 20-0567-02 which has a center lower port (picture below shown with Fuel Rail Adapter 20-0372)

If the engine is turbocharged or uses a centrifugal supercharger

The OEM venturi jet pump in the return line creates a restriction that can impact fuel pressure reliablity
