The PPE Race Fuel Valve for LB7 Duramax (heat treated stainless steel) replaces stock or a shimmed pressure relief valve.

This valve helps maintain fuel rail pressure during high engine load conditions. It eliminates potential low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient pressure relief valve spring pressure opening, returning fuel to the fuel tank.
