Review on 🔧 Ultimate Performance Delphi FP10300 Fuel Injection Pressure Regulator: Boost Engine Efficiency and Optimized Fuel Delivery by Cary Clemons

Chevrolet Impala 2003. Precision fit including upper shaft which is important for the vacuum system. Delphi generally makes reliable parts. Replaced the original that was leaking; It works well. Installation is a chore - you have to remove the air intake system to access the fuel line screw and bolt. Install outdoors. Gas flows out of the fuel line even after the fuel line is depressurized. Youtube videos show how to do it, but they also claim it can be installed without removing the air system. Not this car this time. Great price, fast delivery, accurate details. Also change the fuel filter with this repair as you will depressurize the fuel line. Be careful when restarting as there will be air in the fuel line. Have your mechanic do it because of the fuel splatter.
