Install
Lubricate the fuel connector o-ring and the threads on the
fuel connector retaining nut.
Carefully insert the fuel connector, aligning the guide ball
with the slot in the cylinder head at the 12-o'clock position.
NOTE: Use even axial force when installing to prevent the
possibility of damage. Make sure not to tear the o-ring as
the connector is being installed.
NOTE: If the injector was removed along with the high-
pressure connector, the installation steps must be
followed. Refer to Procedure 006-026 in Section 6.
Tighten the fuel connector retaining nut.

Finishing Steps
WARNING
Make sure the fuel inlet and return valves are returned
to the open position before cranking engine. Engine
damage can result if valves are in the wrong position
when engine is cranked or started. Environmental
damage can also occur. Refer to Procedure 006-999 in
Section F.
• Install the high-pressure injector supply line. Refer to
Procedure 006-051 in Section 6.

• Operate the engine and check for leaks.
Fuel Rail (006-060)
General Information
WARNING
The fuel pump, high-pressure fuel lines, and fuel rail
contain very high-pressure fuel. Do not loosen any
fittings while the engine is running. Wait at least 10
minutes after shutting down the engine before
loosening any fittings in the high-pressure fuel
system to allow pressure to decrease to a lower level.
CAUTION
Make sure the fuel inlet and return valves are returned
to the open position before cranking engine. Engine
damage can result if valves are in the wrong position
when engine is cranked or started. Environmental
damage could also occur. Refer to Procedure 005-999
in Section F for further information.
Due to the number of different fuel rail configurations, the
steps in this procedure have been written to be generic.
Some of the illustrations are not representative of the
parts being removed or installed.
