PPE Race Fuel Valve, 2007.5-2018 6.7L Cummins, 2004.5-2010 GM 6.6L

Fuel Pressure At The Fuel Rail Is Monitored By The Fuel Rail Pressure Sensor. If Fuel Pressure Becomes Excessive, The Pressure Limiting Valve Opens And Vents Excess Fuel Pressure Vents Through The Fuel Pressure Limiting Valve Drain Port. One of the most common issues causing hard starts, lack of power, and poor fuel economy, is a wore or weak pressure relief 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.
