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

Insufficient pressure from the relief valve spring leads to diagnostic trouble codes you'd rather not see. Pacific Performance Engineering race fuel valve O-rings combine with the stainless steel valve itself to maintain fuel rail pressure during heavy engine load conditions. They block the pressure relief port completely, preventing fuel return to the tank. These Viton® O-rings are made from chemical-resistant rubber--better quality than the OEM O-ring for a longer part life. Eliminate potential low fuel rail pressure DTC codes P1093 and P0087 during power enrichment, courtesy of Pacific Performance Engineering race fuel valve O-rings.

Why go to the trouble of modifying your stock fuel rail when you can simply have Pacific Performance Engineering do it for you? They do all the work; you get a PPE high performance fuel rail and all the benefits of a fully modified part. Equipped with both the PPE race fuel valve (or release valve shim kit style available by request) and ported fuel rail fitting, these PPE units are ready to bolt-on and run. This modification helps to maintain fuel rail pressure during full-throttle driving and also eliminates low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are generally caused by insufficient PRV spring pressure.
