Attention! The fuel system is under pressure! Be sure to depressurize the high pressure area before opening the system.
1. Connector: fuel pressure regulator-N276-
2. High pressure pump screw: replacement; 1.8 l engine: 8 Nm + turn 90° (¼ vol.), 2.0 l engine: 20 Nm
3. Fuel pressure regulator -N276-
4. High pressure pump: there is an electric fuel pump in the fuel tank, which supplies fuel to the mechanical fuel pump; when installing the high pressure pump, make sure that no impurities enter the fuel system; there should be no overpressure in the fuel system; install fuel lines without stress; check O-ring, replace if damaged
5. O-ring: replace if damaged
6. Roller follower: under certain conditions, after removing the high pressure pump remains in the vacuum pump
7. Fuel supply fitting: 1.8L engine: 15Nm, 2.0L engine: 20Nm
8. Collar: replace
9. Pressure fuel line: to the fuel rail of the MPI injectors; lay without tension (cleanliness)
