INSTALLATION
High-pressure lines are used between the fuel
injection pump and the fuel injectors only. 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: Be sure that the high-pressure fuel lines
are installed in the same order that they were
removed.
(1) Lubricate threads of injector line fittings with
clean engine oil.
(2) Loosen, but do not remove, all fuel line support
bracket bolts.
