Removing
1. Relieve fuel pressure in the fuel line («Fuel Line - Pressure Relief»).
2. Remove the receiver («Inlet manifold receiver - removal, replacement of seals and installation»).
Comment. If you do not remove the receiver, then during assembly it is difficult to ensure the necessary cleanliness of the nozzles.
3. Pressing on the spring clips, disconnect the wiring harness pads from the four injectors.
4. With a 17 mm open-end wrench, unscrew the ramp fitting, holding the hex end of the fuel line hose with a wrench of the same size.
5. We remove the hose tip from the fuel rail fitting and, prying it with a slotted screwdriver, remove the rubber sealing rings from the ends of the tubes.
Warning! Replace damaged sealing rings.
6. With a 5 mm hex wrench, unscrew the two bolts securing the fuel rail to the intake manifold.
7. Remove the fuel rail assembly with injectors.
Attention! Be careful! There is a small amount of fuel left in the fuel rail.
Disassembly
1. Remove the latch with a slotted screwdriver.
2. Remove the nozzle from the fuel rail.
3. 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. Replace damaged sealing rings.
4. 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, lubricate the O-rings with engine oil.
