PPE Race Fuel Valve - LB7 Duramax 2001-2004

Upgrade the fuel system in your 2001-2004 GM 6.6L Duramax LB7 with the PPE 113072800 Race Fuel Valve. The PPE Race Fuel Valve (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.
