rail on the intake manifold. Lift up on the rails
evenly and remove all eight injectors.
D. Using a small amount of clean motor oil, lightly
lubricate the O-rings on both ends of the Vortech
supplied fuel injectors.
E. Install the new injectors into the fuel rails with
the terminals facing outward.
F. Carefully lower the fuel rail/injector as-
sembly down onto the intake manifold.
2009-2010 5.7L Challenger Only: Fuel Rail
must be mounted 180° from original position so
that fuel inlet is now located on the passenger
side.
G. Check to see that each injector has been seated
properly into the intake manifold.
H. Tighten down the passenger side of the fuel rail
assembly with the original bolts and attach the
injector plugs to the injectors.
I. (5.7L vehicles only) Cut the engine cover
mounting pedestals off of the two driver side
fuel rail fasteners.

hose as shown in Fig. 3-b.
L. Tighten a stepless clamp on each hose connec-
tion.

line next to the brake booster and install the
aluminum MAP sensor block assembly. In-
stall a clamp on each connection. Unplug
the connector from the factory MAP sensor
on the back of the intake manifold and plug it

line next to the brake booster and install the sup-
plied TEE. Install a clamp on each connection.
Remove the factory MAP sensor from the back
of the intake manifold. Install the supplied MAP
