Removal Procedure

Caution: Fuel Vapors can collect while servicing fuel system parts in enclosed areas such as a trunk. To reduce the risk of fire and increased exposure to vapors:

   • Use forced air ventilation such as a fan set outside of the trunk.
   • Plug or cap any fuel system openings in order to reduce fuel vapor formation.
   • Clean up any spilled fuel immediately.
   • Avoid sparks and any source of ignition.
   • Use signs to alert others in the work area that fuel system work is in process.

  1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
  2. Drain the fuel tank. Refer to Fuel Tank Draining .
  3. Disconnect the fuel tank fuel feed pipe from the chassis fuel pipe near the fuel tank. Refer to Plastic Collar Quick Connect Fitting Service .
  4. Disconnect the fuel tank return pipe from the chassis fuel return pipe near the fuel tank. Refer to Plastic Collar Quick Connect Fitting Service .
  5. Disconnect the evaporative emission (EVAP) vapor near the rear of the fuel tank.

  2. Object Number: 104646  Size: SH

    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.
