Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the right fuel rail mounting bolts to 25 N·m (18 lb ft).
Tighten
Tighten the left fuel rail mounting bolts to 25 N·m (18 lb ft).
Caution: Improper torque methods of the fuel lines will result in fuel leaks and possible damage to the engine. Failure to follow proper fuel line fitting torque methods could result in serious personal injury.
Tighten
Tighten the injection pipes to 41 N·m (30 lb ft)
Notice: Ensure proper torquing of the fuel injector line. An under-torqued fuel injector line will not seal properly and an over-torqued fuel injector line may damage the fuel injector fitting. An improperly sealed or damaged fuel injector line or fuel injector fitting will cause a fuel leak.
Tighten
Tighten the anti-rotation lock bolts to 4 N·m (35 lb in)
Caution: Improper torque methods of the fuel lines will result in fuel leaks and possible damage to the engine. Failure to follow proper fuel line fitting torque methods could result in serious personal injury.
