Note. The following procedure applies to models where the fuel pressure regulator is installed on the fuel rail. On later models, the regulator is mounted on the top of the fuel tank or integrated with the fuel pump. The tank-mounted regulator can be accessed by removing the fuel tank (see paragraph 10). Regulators integrated with the fuel pump are not supplied separately.
Note. Before starting work, read the warning given in paragraph 1.
17. Disconnect the ground wire from the battery (see «Disconnecting the battery»).
18. Disconnect the vacuum pipeline from a regulator. Keep in mind that on early engines, while the fuel rail is in place, access to the regulator is difficult. Therefore, if necessary, remove the fuel rail as described above, and then remove the regulator.
19. Considering the information given in paragraph 7, cover the regulator with a thick layer of rags to prevent a possible jet of fuel under pressure, then remove the clip and remove the regulator from the fuel rail.
20. Installation is carried out in the reverse order of removal. Inspect the regulator seal for signs of damage or deterioration and replace if necessary.
