Kia Optima: Release Residual Pressure in Fuel Line
|
Whenever the high pressure fuel pump, fuel pipe,
delivery pipe, or injector is removed immediately after shutting off
the engine, an injury may be caused by the release of highly pressurized
fuel. Release the residual pressure in the high pressure fuel line by
referring to the "Residual fuel pressure release procedure" below before
removing any high pressure fuel system components.
