1.
A 1 ⁄
2
-inch NPT female pipe thread
port must be provided at the rear of
the intake manifold plenum area for
the shuttle valve vacuum line. Drill and
tap into the manifold at the
approximate location of the elbow
fitting shown in
Figure 25. Check that
your proposed location will allow the
45°
1 ⁄
2
" NPT x –10AN elbow to be
rotated 360° when tightened. If any
additional vacuum/boost components
are to be connected to the rear of the
manifold plenum (MAP sensor, boost
gauge, fuel pressure regulator ref.,
etc.), drill and tap the necessary pipe
thread ports as shown in
Figure 25
above the elbow fitting. Many EFI
throttle bodies provide alternative
ports to connect these components.
Install pipe plugs (not supplied) in any
ports not used.
Note: This operation is best performed
with the manifold removed. Always
properly clean before installation.
2.
Apply liquid Teflon to the pipe
threads of the 1 ⁄ 2 " x -10 AN 45º fitting
and install into the back of the intake
manifold. Aim the fitting approximately
as shown in
Figure 25.
3.
Install the four 5 ⁄ 16 " x 6.5” studs
into the manifold until bottomed.
4.
Thread two 5 ⁄ 16 " fine thread hex
nuts onto one of the studs.
5.
Lock the nuts together by turning
them in opposite directions toward
each other. See
Figure 26
6.
Once the nuts are locked together
use a wrench to snug the stud into the
intake manifold by turning the upper
nut. (Approx 5-8 ft-lbs).
7.
Loosen the nuts by turning them in
the opposite direction and remove
them from the stud.
8.
Repeat Steps 4 – 7 for the
remaining three studs.
