Slowly slide SST (guide) toward the tip of the fuel injector set. When the fuel injector set contact surface of SST (guide) aligns with the fuel injector seal (fuel injector set tip side) as shown in the illustration, hold the position for 5 seconds or more to fully align the fuel injector seal into the fuel injector set groove.
Note
Be careful that the fuel injector seal is not pinched between SST (guide) and the fuel injector set groove. Replace the fuel injector seal if it becomes damaged.
Tech Tips
Set SST (guide) so that its bottom surface and the fuel injector seal are flush.
If there is difficulty in sliding SST upward, slowly wiggle it from side to side while sliding it up the fuel injector set little by little.
| *a | Normal |
| *b | Protruding |
| *c | Deformed |
| *d | CORRECT |
| *e | INCORRECT |
