| *5 | O-ring | - | - |
| *a | Opening | *b | Overlapped |
| *c | Stretched | *d | Correct |
| *e | Incorrect | - | - |
Note
Check that there is no foreign matter or damage on the O-ring groove of the fuel pipe plug sub-assembly.
Check that the No. 1 fuel injector back-up ring and No. 3 fuel injector back-up ring are installed in the correct orientation.
Make sure that the No. 1 fuel injector back-up ring, No. 2 fuel injector back-up ring, No. 3 fuel injector back-up ring and O-ring are installed in the correct order.
Check that the opening of the No. 1 fuel injector back-up ring is not overlapped or stretched as shown in the illustration.
After installing the O-ring, check that it is not contaminated with foreign matter and is not damaged.
Install the dust cap sub-assembly to the fuel pipe plug sub-assembly.
Install a new gasket to the fuel pipe plug sub-assembly as shown in the illustration.
Secure the fuel delivery pipe in a vise between aluminum plates.
Note
Do not overtighten the vise.
Using a 5 mm hexagon socket wrench, install the fuel pipe plug sub-assembly to the fuel delivery pipe with the 2 bolts.
Remove the fuel delivery pipe from the vise.
