When removing and installing an injector, always renew the following components and seals/O-rings:
“copper seal”, “O-ring for injector bore”, “O-ring for injector return connection”.

Removed injectors must always be reinstalled in their original location (on the same cylinder).

Before reusing “high-pressure line”, perform a visual check of taper seats for damage such as trans-
