Pacific Performance Engineering Race Fuel Valve O-Rings

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.
