Use care in removing injectors to prevent damage
to the electrical connector pins on the injector and
the nozzle. The fuel injector is serviced as a
complete assembly only. Since it is an electrical
component, it should not be immersed in any type
of cleaner. Support the fuel rail to avoid damaging
other components while removing the injector.
