Removal
1. Relieve the fuel pressure in the fuel line (see "Fuel line - pressure relief")
2. Remove the receiver (see "Receiver - removal and installation").
3. By pressing the spring clips, disconnect the wiring harness connectors from the four injectors.
4. With an open-end wrench by 17 mm we unscrew the fuel rail fitting, holding the hexagonal 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. With a hex key by 5 mm we 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. Any damaged sealing rings must be replaced.
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, we cover the sealing rubber rings of the injectors with a thin layer of motor oil.
