Do not loosen the high-pressure fuel lines to remove
air from the fuel system. This procedure is not
required.
Visually inspect the high-pressure fuel lines before
the engine is started. This inspection should be each
day.
If you inspect the engine in operation, always use the
proper inspection procedure to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, “General hazard Information”.
• Inspect the high-pressure fuel lines for damage,
deformation, a nick, a cut, a crease, or a dent.
• Do not operate the engine with a fuel leak. If there
is a leak, do not tighten the connection to stop the
leak. The connection must only be tightened to the
recommended torque. Refer to Disassembly and
Assembly, “Fuel injection lines - Remove and Fuel
injection lines - Install”.
• If the high-pressure fuel lines are torqued correctly
and the high-pressure fuel lines are leaking, the
high-pressure fuel lines must be replaced.
• Ensure that all clips on the high-pressure fuel lines
are in place. Do not operate the engine with clips
that are damaged, missing, or loose.
• Do not attach any other item to the high-pressure
fuel lines.
• Loosened high-pressure fuel lines must be
replaced. Also removed high-pressure fuel lines
must be replaced. Refer to Disassembly and
assembly manual, “Fuel Injection Lines - Install”.
