Attention! The fuel in the lines is under pressure, spilled fuel must be collected and sent for disposal.
Distribution line replacement (1, see fig. 4.19) power supply systems assembly must be carried out in the following order. Prepare a container and rags to collect spilled fuel, turn off the ignition and remove the soundproof casing.
Mark the loops (1, fig. 4.141) knock sensors. Disconnect IIIC (2) from the switching EMC. Disconnect loops (3) intake camshaft position sensors from the wiring board. Remove the plugs on the left casing of the ignition coils and disconnect the loops from the ignition coils.
Loosen the nuts (arrows, fig. 4.142) and disconnect the wiring strip from the injectors. Put aside the switching EMC (2) along with the holder. Disconnect the vacuum line from the vacuum chamber (3). vacuum cavity (3) set aside with the holder. Disconnect the wiring harness (4) from injectors (nozzles) and put it aside.
Note. When pipes and hoses are disconnected, fuel flows out, collect it and send it for disposal.
Disconnect the fuel line (1, fig. 4.143) from distribution line (ramps). Loosen clamp (2) and disconnect the hose (3).
Loosen the nuts (arrows, see fig. 4.144) and remove both retaining brackets (1 and 2). Pull out the distribution line (3) with the injectors upwards and remove it together with the injectors (nozzles). Remove the fuses-brackets and remove the injectors from the distribution line.
Before installing injectors, check their O-rings. To facilitate the installation of the camshaft, lubricate the O-rings (round section) injectors (nozzles) fuel injection thin layer lubrication type «technical vaseline».
When installing a narrow (see fig. 4.139) and wide jumpers connecting with «weight», fix them with a bolt on the ignition coil of the 7th cylinder.
