6.6L Duramax Race Fuel Valve

The PPE Race Fuel Valve, made from 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 an insufficient pressure relief valve (PRV) spring pressure. This leads to the valve opening too early which causes excessive amounts of fuel to be returned to the tank.
