2. High pressure pump screw: replacement; 1.8L engine: 8 Nm + 90° (¼ turn), 2.0L engine: 20 Nm
3. Fuel pressure regulator "N₂76"
4. High pressure pump: There is an electric fuel pump in the fuel tank that supplies fuel to the mechanical fuel pump; when installing the high-pressure pump, make sure that no contaminants enter the fuel system; there should be no increased pressure in the fuel system; install fuel lines without causing stress; check the O-ring, replace if damaged
