·Install new fuel lines and hand tighten the nuts on each end of the fuel lines. · Install clamps (15), (19), (20), and (23). Thread the nuts by two full turns. Failure to place grommet correctly on the fuel line could result in a failed fuel line. · Tighten the fuel nut at the fuel rail to a torque of 27 ± 3 N·m (20 ± 2 lb ft). Repeat for the remaining cylinders. · Tighten the fuel nut at the pump and the quill assembly to a torque of 15 ± 3 N·m (135 ± 27 lb in). Then, turn the nut clockwise an additional 60° ± 5°. Repeat for the remaining cylinders. |

Removal Procedure
 |
Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death. |
 |
| NOTICE |
|---|
Contact with high pressure fuel may cause personal injury or death. Wait 60 seconds after the engine has stopped to allow fuel pressure to purge before any service or repair is performed on the engine fuel lines. |
| NOTICE |
|---|
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Dispose of all fluids according to local regulations and mandates. |
| NOTICE |
|---|
Cleanliness is an important factor. Clean the exterior of the engine thoroughly before the removal procedure. Ensure the area around the Fuel Manifold and the Fuel Lines are thoroughly cleaned. This action will prevent contaminants from entering the internal mechanism. Before replacing any Fuel Lines, follow the instructions that are listed below. Replace the Fuel Lines with the correct Fuel Lines Group. |

Installation Procedure
| NOTICE |
|---|
Fuel injection lines MUST only be used once. Discard all fuel injection lines after use. |
| NOTICE |
|---|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Note: Make sure that the fuel line caps remain in position until the fuel line is positioned near the corresponding ports in order to prevent contamination. Ensure that the areas around the rail and fuel lines are thoroughly clean before continuing this procedure. If any parts are worn or damaged, use new parts for replacement. Cleanliness is an important factor. Ensure that no debris gets introduced into the fuel system during the installation procedure. If any parts are worn or damaged, use new parts for replacement.
