NOTICE
• Always use new O-rings.
• When installing the injectors, do not allow
any foreign material to enter or adhere to
the injectors, fuel rails, or O-rings.
• Be careful not to twist or pinch the O-rings
when installing the injectors.
• When installing the injector, install it at the
same position as the removed cylinder.
• If an injector is subject to strong shocks or
excessive force, replace it.
• If installing the original fuel rail and bolts,
remove the white paint marks using a
cleaning solvent. Otherwise, paint chips on
the bolt seats could prevent the bolts from
being tightened to the specified torque.

tor.
