REMOVAL
CAUTION: Cleanliness cannot be overemphasized when handling or replacing diesel fuel system components. This especially includes the fuel
injectors, high-pressure fuel lines and fuel injection pump. Very tight tolerances are used with these parts. Dirt contamination could cause rapid part wear
and possible plugging of fuel injector nozzle tip holes. This in turn could lead to possible engine misfire. Always wash/clean any fuel system component
thoroughly before disassembly and then air dry. Cap or cover any open part after disassembly. Before assembly, examine each part for dirt, grease or
other contaminants and clean if necessary. When installing new parts, lubricate them with clean engine oil or clean diesel fuel only.
1. Disconnect both negative battery cables from both batteries. Cover and isolate ends of cables.
2. Thoroughly clean fuel lines at both ends.
3. If removing fuel line at either #1 or #2 cylinder, the intake manifold air heater elements must first be removed from top of intake manifold. Refer
to Intake Air Heater Removal / Installation for procedures.
4. If removing fuel line at #6 cylinder, a bracket (1) is located above fuel line connection at cylinder head. Two bolts secure this bracket to rear of
cylinder head. The upper bolt hole is slotted. Loosen (but do not remove) these 2 bracket bolts. Tilt bracket down to gain access to #6 fuel line
connection.
5. Remove engine lift bracket (if necessary).
6. Remove necessary insulated fuel line support clamps (2) at intake manifold. DO NOT remove insulators from fuel lines.
