The PPE High Performance fuel rail with Race Fuel Valve will block the fuel pressure relief valve. This eliminates the low fuel rail pressure DTC codes P1093 & P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient PRV spring pressure. Replaces stock or shimmed pressure relief valve. This completely blocks the pressure relief port deadheading the fuel rail.
