(10) Gently rock and pull the left fuel rail until
the fuel injectors just start to clear the intake mani-
fold. Gently rock and pull the right fuel rail until

fold. Repeat this procedure (left/right) until all fuel
injectors have cleared the intake manifold.
(11) Remove fuel rail (with injectors attached)
from engine.
(12) Remove the clip(s) retaining the injector(s) to
