Removal / Inspection / Installation
Warning
l Before performing the following operation, release the fuel pressure from the fuel system to
reduce the possibility of injury or fire. (Refer to page F-121 .)
l When removing the fuel tank, keep sparks, cigarettes, and open flames away from it.
l Before repair the fuel tank, clean it throughly with steam to remove all explosive gas.
1. Remove in the order shown in the figure.
2. Inspect the fuel tank components visually and repair or replace if necessary.
3. Install in the reverse order of removal, referring to
Installation Note.
