Most modern fuel injected cars run a fuel pump in the tank and run much more fuel than is needed to the fuel rail. A regulator keeps a certain amount of fuel pressure in the rail and then sends the rest back to the tank. The Sard adjustable fuel regulator can adjust the amount of fuel entering your engine by turning an adjustment part. Your factory one on your vehicle cant adjust the fuel pressure and when you start running more power into your vehicle you need more fuel. Hence where these are perfect for you!
