Attention! Before performing the operation, read the safety precautions for maintenance and repair of the power system (see "Safety measures for the maintenance and repair of the power system").
Removing
1. Relieve fuel pressure in the fuel line (see "Fuel Line - Pressure Relief").
2. Remove the receiver (see "Engine receiver 2111 (1,5i 8v) - removal, replacement of seals and installation").
Comment.The receiver can not be removed, but then it is difficult to ensure the necessary cleanliness of the nozzles during assembly.
3. Pressing on the spring clips, disconnect the wiring harness pads from the four injectors.
4. Remove the hose from the nozzle of the fuel pressure regulator.
5. Open end wrench by 17 mm unscrew the fitting of the fuel supply pipe to the ramp (1), while holding the hex end of the fuel line hose with a wrench of the same size. Similarly, disconnect the fuel drain pipe from the hose (2). The drain pipe connection is marked with blue paint at the factory.
6. We remove the tips of the hoses from the tubes.
7. Hex key by 5 mm unscrew the two bolts securing the fuel rail to the intake manifold.
8. Remove the fuel rail assembly with injectors.
Attention! Be careful, there is a small amount of fuel left in the fuel rail.
9. Prying with a slotted screwdriver, remove the rubber o-rings from the ends of the tubes.
Warning! Replace damaged sealing rings.
Disassembly
10. Use a slotted screwdriver to shift the nozzle retainer along the fuel rail.
11. Remove the nozzle from the fuel rail.
12. Similarly, remove the other three nozzles.
Warning! The connections of the injectors with the fuel rail and with the inlet pipeline are sealed with rubber rings. Any damaged O-rings must be replaced.
13. Remove the injector spring clamps from the fuel rail.
14. Remove the fuel pressure regulator (see "Fuel rail engine 2111 (1,5i 8v) - replacement of the fuel pressure regulator").
15. Key by 24 mm unscrew the nut of the fuel supply pipe and remove the end of the pipe from the fuel rail.
Warning! The connection of the tube with the fuel rail is sealed with a rubber ring installed at the end of the rail. Replace damaged sealing ring.
16. If necessary, use a metal cap from the wheel nipple to unscrew the spool of the diagnostic fitting.
Assembly and installation
We assemble and install the fuel rail in reverse order. Before assembly, coat the O-rings with a thin layer of engine oil.
