Fuel Injector Removal And Installation: Installation
- Replace injector O-ring (3) with new one using care not to damage it. Install grommet (2) to injector.
- Check if insulator (1) is scored or damaged. If it is, replace with new one.
Install insulators (1) and cushions (4) to intake manifold or cylinder head.
- Apply thin coat of fuel to O-ring (1) and then install injectors into delivery pipe and intake manifold or cylinder head.
Make sure that injectors rotate smoothly. If not, probable cause is incorrect installation of O-ring.
Replace O-ring with new one.
- Tighten delivery pipe bolts and make sure that injectors rotate smoothly.
