Removal Procedure

Caution : To reduce the risk of fire and personal injury that may result from a fuel leak, always replace O-ring seals exposed during component services.

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  1. Remove negative battery cable(s).
  2. Loosen filler cap(s) to relieve tank pressure.

    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.

  3. Install both fuel lines on the fuel pump.
  4. Tighten
    Use a backup wrench in order to prevent the pump from turning. Tighten the fuel line fittings to 30 N·m (22 lb ft).
