SUBJECT:

DD Platform High Pressure Fuel Lines

NOTE: This document supersedes 14 TS-19.
ISSUE
With the exception of the return lines P-clip bolt on the two-filter system, the components in the
images below, from the high pressure fuel pump to the fuel rail, are no longer reusable; they are
ONE-TIME-USE only.

NOTICE:
DO NOT install any high pressure fuel line bolts and fittings using power tools.
All bolts and fittings MUST be installed and torqued to specification using
hand tools to prevent damage and possible fuel leakage.

PERSONAL INJURY
All parts provided within this kit must be installed in the proper locations, and
MUST be fastened to the specified torque. Failure to properly torque
hardware/components will result in failure of a high pressure fuel feed line,
resulting in possible fire and/or personal injury.

PERSONAL INJURY
All parts provided with this kit, and those they are replacing on the engine,
function as a complete system and are single-use items. The old parts cannot be
reused. Reusing parts or failing to use all new parts contained in the kit may
result in the failure of high pressure fuel lines, possibly resulting in a fire.

REQUIRED ACTION
The high pressure fuel rail feed lines from the high pressure fuel pump to the fuel rail,
mounting bracket, P-clips, vibration dampers, return lines p-clip (engine mounted three-filter fuel
system only), mounting bracket bolts, P-clip bolts, vibration damper bolts, and return lines P-clip
bolt (engine mounted three-filter fuel system only) MUST be replaced if one of these parts are
removed from the engine during any repair.
All five kit numbers listed below have permanent vibration dampers (1) installed on the high
pressure fuel rail feed lines.

Table 1 provides a list of the correct service kit part numbers.

ADDITIONAL INFORMATION
Reference Technical Service letter 13 TS-5 for additional information on the differences
between the engine mounted two- and three-filter fuel system.
The return lines P-clip is not removed on the two-filter fuel system.
The return lines P-clip bolt is reused in the two-filter fuel system.
Refer to the appropriate section of Power Service Literature for removal and installation
information.
Refer to video on DDCSN > Support > Multimedia > DD Platform > High Pressure Fuel Lines.

NOTICE:
DO NOT install any high pressure fuel line bolts and fittings using power tools.
All bolts and fittings MUST be installed and torqued to specification using
hand tools to prevent damage and possible fuel leakage.

Tape has been added to the outside of the service kit box to further highlight the need to follow
