Adapter Plate Installation

1. Pull back the trunk liner, push out the fuel filler door striker.

2. Remove the fuel filler door.





3. From underneath the car, check the rear edge of the filler pipe mounting surface where it joins with the wheelwell. Look for signs of rust-through into the trunk. Any holes will have to be sealed later in this procedure to prevent water leakage into the trunk.

4. Use a wire brush to clean the rust out of the mounting cup.





5. Coat the inside of the mounting cup with a 1/4" thick coat of 3M Ultra Pro Brushable Seam Sealer (see REQUIRED MATERIALS). Make sure any rust-through areas you found in Step 3 are completely sealed.

6. Place the adapter plate inside the mounting cup. Install the striker.

7. Remove the excess sealer around the outside edges of the adapter plate.

8. Temporarily install the fuel filler door.





9. Using the holes in the adapter plate as a guide, drill four 1/8" diameter holes in the mounting cup.

10. Install four of the pop rivets that came with the adapter.

11. Adjust the fuel filler door alignment.

^ Loosen the mounting bolts and adjust the door so the top and bottom gaps are equal and the door sits flush with the fender line. Tighten the bolts.





^ The door has moved backwards the thickness of the adapter plate. To realign it, use a hammer handle to bend the hinge forward slightly.





12. Working inside the wheelwell, smooth out the sealer so it forms a continuous, waterproof seam between the adapter plate and mounting cup. Apply a thick coat of sealer to any rust through areas you found in Step 3.

13. Reinstall the trunk liner.

14. Go to COMPLETION PROCEDURE.
