Replaces stock or shimmed pressure relief valve. This valve completely blocks the pressure relief port (effectively deadheading the fuel rail). Eliminates low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient PRV spring pressure. Helps maintain fuel rail pressure during full throttle driving.
