19.INSTALL FUEL INLET PIPE SUB±ASSY
NOTICE:

In case of having the common rail replaced, must re-
place fuel inlet pipe, too.

When assembling the pipe, perform the operation
with the engine cold under room temperature.
(a)Temporarily install the fuel inlet pipe.
(b)Using SST, tighten the nut of the fuel inlet pipe to the com-
mon rail side.
