REMOVAL AND INSTALLATION (Continued)

HIGH-PRESSURE LINES
All high±pressure fuel lines are of the same length
and inside diameter. Correct high±pressure fuel line
usage and installation is critical to smooth engine
operation.
CAUTION: The high±pressure fuel lines must be
clamped securely in place in the holders. The lines
cannot contact each other or other components. Do
not attempt to weld high±pressure fuel lines or to
repair lines that are damaged. Only use the recom-
mended lines when replacement of high±pressure
fuel line is necessary.
REMOVAL
(1) Disconnect negative battery cable from battery.
(2) Remove the necessary clamps (Fig. 58) holding
the lines to the engine.
(3) Clean the area around each fuel line connec-
tion. Disconnect each line at the top of each fuel
injector (Fig. 59).
(4) Disconnect each high±pressure line fitting at
each fuel injection pump delivery valve.
(5) Very carefully remove each line from the
engine. Note the position (firing order) of each line
while removing.Do not bend the line while
removing.
CAUTION: Be sure that the high±pressure fuel lines
are installed in the same order that they were
removed. Prevent the injection pump delivery valve
holders (Fig. 58) from turning when removing or
installing high±pressure lines from injection pump.
INSTALLATION
(1) Carefully position each high±pressure fuel line
to the fuel injector and fuel injection pump delivery
valve holder in the correct firing order. Also position
each line in the correct line holder.
(2) Loosely install the line clamp/holder bolts.
(3) Tighten each line at the delivery valve to 30
N´m (22 ft. lbs.) torque.
(4) Tighten each line at the fuel injector to 30 N´m
(22 ft. lbs.) torque.

REMOVAL AND INSTALLATION (Continued)

Be sure the lines are not contacting each
other or any other component.
(5) Tighten the clamp bracket bolts to 24 N´m (18
ft. lbs.) torque.
(6) Bleed air from the fuel system. Refer to the Air
Bleed Procedure section of this group.
