NOTICE: Removal/installation of the Hydrocarbon (HC) doser block assembly will require that the system be
purged to remove all air in the fuel lines. Refer to DDDL 7.X to perform this routine service.
1. Install the HC doser block assembly (2) using three bolts (3); torque bolts to 32-36 N·m (24-27 lb·ft).

2. Plug in connectors to the Fuel Cutoff Valve (FCV), Fuel Doser Line Pressure Sensor (FLP), Fuel Compensation
Pressure Sensor (FCP), and the Electronic Dosing Valve (EDV).
3. Connect the inlet and outlet fuel lines to the HC doser block assembly. Torque the banjo bolt for GHG14 DD15 AT to
15 N·m (11 lb·ft) and for all others models 25 N·m (19 lb·ft)
4. Connect the air compressor inlet hose from the doser bracket (if equipped).
5. Tighten all connections securely.
WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level
surface, parking brake is set, and the wheels are blocked.
WARNING: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area.
Engine exhaust is toxic.
6. Start the engine.
NOTE: It may take more than one purge attempt to completely purge all of the air from the fuel line. Do not
exceed three purge attempts.
7. Use the HC doser command to run the purge function in DDDL 7.X to purge all the air from the doser valve and line.
WARNING: HOT EXHAUST
During parked regeneration the exhaust gases will be extremely HOT and could cause a fire if
directed at combustible materials. The vehicle must be parked outside.
8. Using DDDL 7.X, initiate a parked regeneration.
