Summary: TT: Special Service Tools: Injector Seal Tool Sets. In the event that injector seal repair is required on vehicles equipped with a direct injection fuel system, a Special Service Tool Set is required to properly install the seal onto the injector. As new vehicle configurations have been released, several injector seal tool sets have been distributed to accommodate these new vehicles. There are a total of three injector seal tool sets for Lexus models, located in the appropriate SST cabinets. Each kit contains multiple pieces as shown in the diagram below. The individual pieces must remain together to ensure these tools are used correctly. Refer to the repair manual for the tool information to ensure the correct tool is used for the desired application.
