13. Tighten the rocker arm bracket bolts to the
specified torque (Section 1.0).
14. Align the fuel pipes and connect them to the
injectors and the fuel connectors. Use socket J 8932-01
to tighten the connections to 12-15 lb-ft (16-20 Nm)
torque.
CAUTION: Do not bend the fuel pipes and do
not exceed the specified torque. Excessive
tightening will twist or fracture the flared ends
of the fuel pipes and result in leaks.
