Removal
Whenever the high pressure fuel pump, fuel delivery pipe, delivery pipe or injector is removed immediately after the engine is turned off, injury may be caused by high pressure fuel spray. Release the residual pressure in the high pressure fuel line by referring to the "Fuel Residual Pressure Release Procedure" before removing any high pressure fuel system components.
  1. Release the fuel line residual pressure. (Refer to Fuel System - "Release Fuel Line Residual Pressure")
  2. Turn the ignition switch OFF and disconnect the (-) battery cable.

    Open the clip cover (B) before disconnecting the quick connector. (If equipped with clip)
