Models with M57 engine
1. Remove all pressure pipelines, having previously closed the generator from hit on it of working liquids.
2. Disconnect the pressure sensor connector (see illustration).
3. Using tool no. 13 5 020, release the union nuts (1) on the fuel rail and loosen the union nuts on the injection pump. Disconnect the pressure head pipeline from a fuel distributive highway. Remove the bolts (3) and remove the fuel rail (4).
4. Installation is carried out in the reverse order. Pay attention to the correct installation of the rubber-metal hinge (2).
Models with M57 engine
Removal of the left distributive highway is described below; the right one is removed in the same way.
1. Remove the pressure lines between the fuel distribution line and the injectors.
2. Give union nuts (1, 2 and 3) pressure pipes and remove the bolts (4) on the bracket. Remove the fuel distribution line (5).
3. Installation is carried out in the reverse order. Note the different bolt lengths.
