STEP 9
• For both rails, install an end cap on the front of
the rail and a rail end adaptor on the rear of
each rail and attach the rail mounting tabs with
the supplied ¼”-20 bolts. NOTE!!! Each Rail
mounting tab has a round hole and a slotted
hole. The round holes will attach to the rails.
The slotted holes will attach to the intake
manifold. Use the supplied washers at the
intake manifold end and fuel rail mount tabs.
STEP 7
• Install the supplied Spring Lok fitting into the
side of the passenger rail. Insert (4) injectors
into the passenger side rail.
• Install the original fuel pressure sensor onto the
driver side fuel rail with supplied o-ring and the
supplied 10-32x1/4” BHCS’s. NOTE!!! Measure
these screws from the bottom of the head to
the end first to ensure you are using the
correct hardware here!

STEP 8
• Insert (4) injectors into the driver side rail. Install
the driver side fuel rail and injectors by guiding
the tip of each injector into its respective bung in
the intake manifold. Secure the rail to the intake
manifold by using the supplied hardware.
• Install the passenger side rail and injectors by
guiding the tip of each injector into its respective
bung in the intake manifold. Secure the rail to
the intake manifold using the supplied
hardware. NOTE!!! To ensure clearance
between the fuel rails and ignition coils, use
(1) of the supplied washers under the
mounting tabs and place (1) over the
threaded portion of each bolt that go
through the tabs at the intake manifold.
NOTE!!! Take extreme care when installing
the small button head cap screws (BHCS)
into the fuel rail. Using the wrong length will
penetrate the fuel rail resulting in a fuel leak.
Use the supplied washers underneath the
small BHCS’s. In addition these screws can
easily cross thread.

STEP 11
• Route the stock fuel feed line under the A/C line
and connect to the 5/8” Spring Lok fitting on the
side of the passenger side fuel rail.
• Assemble the cross over hose by pushing the
barbed ends of the supplied 90 degree fittings
into the end of the hose. Tighten the cross over
hose onto the threads of the rail end adaptors
on the back of both rails. NOTE!!! When
routing the cross over hose, be mindful of
hot EGR tube it must pass by. Route so no
contact is made with the EGR Tube.
