Removing
Disconnect:
- battery;
- fuel pressure sensor 1;
- nozzles 2;
- camshaft position sensor.
Disconnect the high pressure fuel lines from the rail by unscrewing the fittings.
Plug the holes with plugs.
Carefully remove fuel rail 3.
Installation
Reinstall the fuel rail and hand-tighten its fastening bolts (while the ramp should be in «floating» position).
Tighten all high pressure pipe fittings by hand (from the injector side, injection pump, then from the rail side).
Tighten all high pressure fuel line fittings (from injector side 1, injection pump 4, then from rail side 2).
Tighten all rail mounting bolts 3.
Note. Each time the rail is removed, it is necessary to replace the fuel return line 5 connected to the injectors.
Fill the system with fuel using the manual priming pump.
After performing any work, check that there are no fuel leaks. Let the engine idle until the electric fan of the cooling system turns on, then increase the engine idle speed several times.
