7.
Drain injector rail by placing a
cup under rear of fuel injector rail and
removing the #6 injector (rearmost).
Tilt fuel injector rail towards cup at
rear.
8.
Remove remaining injectors and
retain securing clips. Injectors should
have O-rings at both ends. Locate and
remove any o-rings that separated
from injectors during removal.
9. Install provided injectors (P/N
43643) into fuel injector rail using
original securing clips. A drop of oil
can be used on o-rings to ease instal-
lation.
!
NOTE: Be careful not to
pinch or cut o-rings when rein-
stalling fuel injectors as this will
cause a major fuel leak.
10.
Reinstall fuel injector rail and
reconnect fuel injector connectors.
Torque to 10 lb-ft.
11.
Reinstall throttle cable/cruise
control cable bracket using provided
spacers (P/N 42730) and bolts (P/N
91759). Torque to 8 lb-ft.
!
NOTE: Bracket varies de-
pending on model year, one
spacer and one bolt may not
be used.
12. After installation of upgraded
fuel injectors, a leak check must be
performed under pressure. To check
for fuel system leaks, turn ignition key
on but do not start engine. This will run
the in-tank fuel pump for a brief time,
which will build fuel pressure in fuel
rail. After keying ignition on, examine
area around the fuel injectors and fuel
rail for any leaks. Turn ignition off and
back on again without starting engine,
and rexamine for leaks. Repeat this
process 4-5 times to insure there
are no fuel system leaks - it may
be helpful to have an assistant during
this process.

NOTE: At this point in the
installation disconnect both
leads to the battery. Leave dis-
connected until installation is
complete.

Carefully scrape intake mani-
fold and throttle body to remove any
debris that will prohibit sealing. Wipe
clean with rag. Ensure that no debris
enters intake.
5.
Install throttle body and spacer
with the provided gaskets (P/N 93078)
on both sides of spacer and secure
