Start from step 8, if it is possible to confirm that the fuel cannot be drained by 30   (7-7/8 US gal, 6-5/8

Imp gal) in advance.

1. Prepare a fuel container and a spare hose.

2. Release fuel pressure from fuel line. Refer to 

EC-463, "Work Procedure"

.

3. Remove the fuel feed hose on the fuel level sensor unit. Refer to 

FL-6, "Removal and Installation"

.

4. Connect a spare fuel hose where the fuel feed hose was removed.

5. Turn ignition switch ON.
6. Drain fuel by 30   (7-7/8 US gal, 6-5/8 Imp gal) from the fuel tank using proper equipment.

7. Confirm that the fuel gauge indication varies.
8. Fill fuel into the fuel tank for 30   (7-7/8 US gal, 6-5/8 Imp gal).

9. Confirm that the fuel gauge indication varies.
