Removal
1. Relieve the fuel pressure in the fuel line (see "Fuel Line - Pressure Relief").
2. Remove the receiver (see above, "1.6i Engine Receiver - Removal, Seal Replacement and Installation").
Note: The receiver does not need to be removed, but then it is difficult to ensure the necessary cleanliness of the injectors during assembly.
3. By pressing the spring clips, disconnect the wiring harness connectors from the four injectors.
4. Using a 17 mm open-end wrench, unscrew the fuel rail fitting while holding the hex end of the fuel line hose with a wrench of the same size.
5. We move the end of the hose away from the fuel rail fitting and, using a slotted screwdriver, remove the rubber sealing rings from the ends of the tubes.
Warning! Replace damaged sealing rings.
6. Using a 5 mm Allen key, unscrew the two bolts securing the fuel rail to the intake manifold.
7. Remove the fuel rail assembly with injectors.
Warning! Be careful! There is a small amount of fuel left in the fuel rail.
Disassembly
1. Remove the retainer using a slotted screwdriver.
2. Remove the injector from the fuel rail.
3. Remove the other three injectors in the same way.
Warning! The connections of the injectors to the fuel rail and to the intake manifold are sealed with rubber rings. We replace damaged sealing rings.
4. If necessary, use a metal cap from the wheel nipple to unscrew the valve stem of the diagnostic nipple.
Assembly and installation
We assemble and install the fuel rail in the reverse order. Before assembly, lubricate the rubber sealing rings with engine oil.
