Pacific Performance Engineering race fuel pressure relief valves are designed to replace the stock pressure relief valve. Manufactured from heat-treated stainless steel, they help maintain fuel rail pressure during heavy engine load conditions. These PPE valves eliminate the potential low pressure DTC codes P1093 or P0087 (during power enrichment) caused by insufficient pressure relief valve spring pressure.
