Execution 1

PERFORMANCE ORDER

Remove withdrawal of the distributive highway with injectors (see the Section Removal and installation of the fuel distributive highway and injectors).

Execution 3

PERFORMANCE ORDER

Remove withdrawal of the distributive highway with injectors (see the Section Removal and installation of the fuel distributive highway and injectors). The regulator of pressure of fuel is located behind on the fuel distributive highway. Location of the regulator of pressure of fuel Disconnect a vacuum hose and remove the fixing bracket. Perform the operations described in paragraphs 3 and 4.

Models with the M52TU engine

PERFORMANCE ORDER

Remove the saloon filter and open the cable channel located on the lower part (2) of its cases. Extend cables outside. Turn out bolts (1) and remove the lower part (2) cases of the saloon filter.
