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 supply pump fixing bolts to 25 N·m (18 lb ft).
Tighten
Tighten the coupling bolts to the following:
| 4.1. | Bolt 1: 91 N·m (66 lb ft) |
| 4.2. | Bolt 2: 61 N·m (46 lb ft) |
| 4.3. | Bolt 1: 60 N·m (45 lb ft) |
Important: When installing the fuel feed pipe on the fuel feed pump, you must use a special gasket between the feed pipe eye (on the relief valve) and the return pipe eye (short return pipe). If you use any other gasket it will cause the engine to not start.
Tighten
Tighten the clamp bolts to 6 N·m (52 lb in).
