| *a | Paint Mark | *b | Correct |
| *c | Incorrect | - | - |
HINT:
If the paint mark on the fuel suction tube with pump and gauge assembly has also moved, tighten the fuel pump gauge retainer until the paint marks are aligned at the original position. Then repeat from step [*1].
(g) Loosen the fuel pump gauge retainer by using SST (fuel pump retainer tool assy) until the fuel pump gauge retainer turns approximately 360°.
| *a | SST (Claw) | *b | SST (Fuel Pump Holding Tool Assy) |
