The fuel rail supplies the injectors with fuel. It is important that the fuel has the necessary pressure at the start of the injection and that there are minimal pressure fluctuations between individual injections.

due to ethanol resistance and crash safety
The high-pressure pump applies system pressure to the fuel, which the fuel rail then delivers to the injectors. The pressure in the fuel rail is adjusted as necessary by a high-pressure pump. A high-pressure sensor on the rail measures the fuel pressure as a control variable. A pressure-limiter valve in the high-pressure pump ensures that the maximum permissible pressure in the fuel rail is not exceeded.
