Answer :

Final answer:

The high-pressure pump is responsible for pressurizing fuel in a common rail fuel system.

Explanation:

Fuel System Components

In a common rail fuel system, the component responsible for pressurizing the fuel to high levels is the high-pressure pump. This pump draws fuel from the fuel tank and delivers it at a high pressure to the fuel rail.

Fuel Filter and Fuel Pressure Regulator

The fuel filter is responsible for removing impurities from the fuel before it reaches the high-pressure pump, while the fuel pressure regulator controls the pressure within the fuel rail, ensuring it stays within the desired range.
