A. Relieve the fuel system pressure
B. Disconnect the eight fuel injector electrical
plugs.
C. Remove the four screws that hold down the
fuel rail on the intake manifold. Lift up on the
rails evenly and remove all eight injectors.
D. Remove the lower O-ring from each of the
supplied injectors and set aside. They will not
be re-used.
E. Replace the lower O-ring on the supplied
injectors with the supplied O-ring.
F. Remove the injector retaining clips from the
factory injectors and install them on the sup-
plied injectors.
G. Using a small amount of clean motor oil,
lightly lubricate the O-rings on both ends of
the Vortech supplied fuel injectors.
H. Install the new injectors into the fuel rails with
the terminals facing outward.
I. Carefully lower the fuel rail/injector assembly
down onto the intake manifold. Check to see
that each injector has been seated properly
into the intake manifold.
J. If the newly installed injectors are longer than
the factory parts, install a supplied (.38"L)
spacer under each fuel rail mounting tab and
use the longer supplied hardware. (Bending
the steel fuel rail capture plate may be neces-
sary to allow raising the fuel rail.)
K. Tighten down the fuel rail assembly.
L. Attach the injector plugs to the injectors using
the supplied adapter harnesses (if needed).
