The Aftertreatment System. The innovative 1-Box ™ Configuration, available only with Detroit ® engines, combines the SCR catalyst, the diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and diesel exhaust fluid (DEF) into one compact component. Combining all of these systems lowers engine back-pressure and reduces overall. For instructions for using the DDR or Pro-Link® 9000, ( see Figure 'Pro-Link 9000'), refer to the Pro-Link Users Manual. For a list of Flash Codes and SAE Fault Codes, refer to '18.4 Code Descriptions'.
The fuel filter and water separator assembly facilitates the settling of water in a collection bowl. See Figure 'Typical Fuel Filter and Water Separator Installation' .

PERSONAL INJURY |
Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.

The purpose of the check valve is to reduce the risk of fuel prime loss and fuel siphoning from the head when the fuel filter is removed. See Figure 'Typical Fuel Return Check Valve Locations' .
Figure 2. Typical Fuel Return Check Valve Locations
NOTICE: |
The check valve must be included in the fuel system. If the check valve is removed for any reason or found to be defective, a new valve must be installed and the fuel system primed before start-up. The R80 — 2.0 mm (0.080 in.) restricted fitting (elbow connector) which is ahead of the check valve must also be included in the fuel system. |
NOTICE: |
Do not increase the size of the orifice in restricted fittings. Increasing restricted fitting hole size can cause injector cavitation, resulting in reduced durability of injectors and other engine components, and increased engine emissions. |
A check valve is connected to a hose in the fuel return line coming from the rear of the cylinder head or at the cylinder head restricted fitting, depending on individual installation requirements. See Figure 'Typical Fuel Return Check Valve Locations' .
Remove the valve as follows:
NOTICE: |
The PRO-CHEK fuel system check valve is installed after the secondary filter. Any dirt or debris entering the fuel system at this point may cause severe injector damage. |
Inspect the PRO-CHEK fuel system check valve as follows:
The PRO-CHEK fuel system check valve is an optional item that, when properly installed, removes air from the fuel supply line between the secondary filter and the cylinder head. No priming is required even after filter change, since any air that may get into the lines is automatically removed when it reaches the PRO-CHEK valve.
Install the PRO-CHEK valve as follows:
1. Secondary Fuel Filter | 4. Air Purge Line |
2. Fuel Inlet | 5. Fuel Outlet |
3. PRO-CHEK Valve | 6. Fuel Spill Line |

Figure 4. Typical Rear-mounted PRO-CHEK Installation
The PRO-CHEK valve is fully assembled and ready to install when received. If the Fuel In or Fuel Out fittings are accidentally loosened or removed for any reason, they must be reinstalled in their proper locations as follows:
Figure 5. PRO-CHEK Valve Cutaway View
NOTICE: |
Fittings must remain clean when installed, since anything that gets inside the PRO-CHEK valve will be carried into the fuel manifold and may damage the injectors. |
NOTICE: |
Do not overtighten the Fuel In or Fuel Out fittings or the top elbow, since this may damage the threads on the fittings or the PRO-CHEK body, resulting in fuel leaks. If fitting or body threads are damaged, the complete assembly must be replaced. |
NOTICE: |
Do not use Teflon® pipe sealant tape on the male pipe fittings, since this may flake off into the fuel system and damage the injectors. |
