PROCEDURE
INSTALL FUEL INJECTOR SEAL
| *a | Area to be Cleaned |
Apply engine conditioner to the area shown in the illustration. Using a piece of cloth, clean carbon deposits from the fuel injector assembly and its grooves.
Note
Do not clean the tip of the fuel injector assembly.
Do not use a wire brush to clean the fuel injector assembly.
If a fuel injector assembly is dropped or the tip of a fuel injector assembly is struck, replace it with a new one.
| *a | SST (Guide) |
| *b | Chamfer |
Apply engine oil to the fuel injector assembly contact surface of SST (guide), then attach SST (guide) to the fuel injector assembly with the chamfer facing the tip of the fuel injector assembly as shown in the illustration.
| *1 | Fuel Injector Seal |
| *a | SST (Holder) |
| *b | Correct |
| *c | Incorrect |
Install a new fuel injector seal to SST (holder).
Note
Be careful not to install the fuel injector seal to SST (holder) at an angle. Doing so will stretch the fuel injector seal.
| *a | SST (Holder) |
| *b | SST (Guide) |
Install SST (holder) with the fuel injector seal to the tip of the fuel injector assembly. Slide the fuel injector seal downward into the fuel injector assembly groove (fuel injector assembly connector side) with your fingers as shown in the illustration.
Tech Tips
Check that the fuel injector seal is seated in the fuel injector assembly groove as shown in the illustration.
Using SST (holder), gently press downward on the fuel injector seal (fuel injector assembly connector side), then slowly slide SST (guide) toward the fuel injector assembly tip to settle the fuel injector seal into the fuel injector assembly groove.
| *a | SST (Holder) | *b | SST (Guide) |
| *c | Press gently | *d | Correct |
| *e | Incorrect | - | - |
Note
Be sure that the fuel injector seal is not pinched between SST (guide) and the edge of the fuel injector assembly groove. Replace the fuel injector seal if it becomes damaged.
Tech Tips
When using SST (guide) to settle the fuel injector seal into the groove, SST (guide) only needs to be slid upward to the position (A) in the illustration.
After using SST (guide) to settle the fuel injector seal into the groove, return SST (guide) to the position (B) in the illustration.

Tech Tips
Check that the fuel injector seal is seated in the fuel injector assembly groove as shown in the illustration.
| *a | SST (Guide) |
Slowly slide SST (guide) toward the tip of the fuel injector assembly. When the fuel injector assembly contact surface of SST (guide) aligns with the fuel injector seal (fuel injector assembly connector side) as shown in the illustration, hold the position for 5 seconds or more to fully seat the fuel injector seal into the fuel injector assembly groove.
Note
Be sure that the fuel injector seal is not pinched between SST (guide) and the edge of the fuel injector assembly groove. Replace the fuel injector seal if it becomes damaged.
Tech Tips
Set SST (guide) so that its bottom surface is flush with the fuel injector seal.
If it is difficult to slide SST (guide) upward, slowly wiggle it from side to side while sliding it up the fuel injector assembly little by little.
Using SST (holder), gently press downward on the fuel injector seal (fuel injector assembly tip side), then slowly slide SST (guide) toward the fuel injector assembly tip to settle the fuel injector seal into the fuel injector assembly groove.
