TIPS FOR SUCCESSFUL INJECTOR INSTALLATION:
- Follow manufacturer installation procedure and torque specifications.
- Thoroughly clean and inspect injector bores (in cylinder head).
- Verify copper combustion seals are installed on new injectors and the old combustion seals were removed with previous injectors.
- Replace fuel filter.
- Replace any fuel lines to avoid contaminating the remanufactured injectors.
