Remove the appropriate caps in order to install fuel injection line (1). Install a new fuel injection line (1) to the fuel injection pump and to the fuel manifold. Refer to Disassembly and Assembly, "Fuel Injection Lines - Install" for the correct procedure.
Position harness assembly (1) and bracket (5) onto the cylinder head. Loosely install bolt (4) and bolt (9) (not shown) to bracket (5) .
Connected harness assembly (1) to coolant temperature sensor (2). Refer to Disassembly and Assembly, "Coolant Temperature Sensor - Remove and Install" for the correct procedure.
Install a new cable strap (3) to harness assembly (1) .Note: Ensure that the new cable strap meets Original Equipment Manufactures (OEM) specifications.
Connected harness assembly (7) to the pressure sensor in the fuel manifold.
Connected harness assembly (16) to the flow control valve.
Connected harness assembly (14) to the fuel temperature sensor. Refer to Disassembly and Assembly, "Fuel Temperature Sensor - Remove and Install" for the correct procedure.
Connected harness assembly (15) to the engine oil pressure sensor. Refer to Disassembly and Assembly, "Engine Oil Pressure Sensor - Remove and Install" for the correct procedure.
Tighten bolt (4) and bolt (9) (not shown) to a torque of 9 N m (80 lb in).
Remove caps from connections for the plastic tube assemblies on fuel injection pump (13). Remove plugs from plastic tube assembly (6) and plastic tube assembly (8) .
Connect plastic tube assembly (6) and plastic tube assembly (8) to fuel injection pump (13) .
