Product Advantages: 1. This valve helps maintain fuel rail pressure under high engine load conditions. 2. Eliminates potential low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment), which are caused by insufficient pressure of the pressure relief valve (PRV) spring. 3. It causes the valve to open too early, resulting in excessive fuel returning to the tank. 4. Easy to install, saving a lot of time. At the same time, it can effectively reduce leakage. 5. It is designed to maintain fuel rail pressure under strong acceleration. Also prevents overnight drain if the standard valve is stuck open or loose. Maintains fuel rail pressure under high engine load conditions. Prevents high pressure fuel from returning to the fuel tank. Eliminates potential low fuel rail pressure DTCs P1093 or P0087 (low fuel rail pressure during power enrichment).
