INSTALLATION - HIGH PRESSURE PUMP
(Refer to 14 - FUEL SYSTEM - WARNING)
CAUTION: Clean sealing surfaces with appropriate
solvents and replace all seals.
NOTE: Inspect then attach high pressure pump
driver and intermediate piece if pump is being
replaced. If wear is present at driver, replace the
intermediate gear.
(1) Position and secure the high pressure pump to
cylinder head (Fig. 5). Tighten bolts to 14 N·m (124
lbs. in.).
CAUTION: NEVER slacken the thread connection.
Use a wrench to counterhold at threaded connec-
tion when slackening and tightening torque in order
to avoid also slackening the threaded connection
the next time.
CAUTION: DO NOT crimp or bend fuel line. Inspect
sealing cone at line; replace line if compression
exists.
NOTE: Care must be taken not to cross the fuel
return and supply lines during installation.
(2) Attach fuel flow supply and return lines (Fig.
5).
(3) Install bracket to high pressure pump (Fig. 5).
Tighten nut to 9N·m (80 lbs. in.).
CAUTION: NEVER slacken the thread connection.
Use a wrench to counterhold at threaded connec-
tion when slackening and tightening torque in order
to avoid also slackening the threaded connection
the next time.
CAUTION: DO NOT crimp or bend fuel line. Inspect
sealing cone at line; replace line if compression
exists.
NOTE: Care must be taken not to cross the fuel
return and supply lines during installation.
(4) Attach high pressure fuel line to pump (Fig. 5).
Tighten to 22N·m (194 lbs.in.).
(5) Install viscous fan clutch (Refer to 7 - COOL-
ING/ENGINE/FAN DRIVE VISCOUS CLUTCH -
INSTALLATION).
(6) Connect negative battery cable.
(7) Refill coolant system with proper mixture to
correct level.
WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS OPERATING. DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOU
