A. Disconnect the electrical plug from the top of
the vacuum pump. Unbolt and remove the
vacuum pump from the brake booster.
Disconnect the 1/2" hose from the barbed
nipple on the vacuum pump.
B. Attach the vacuum pump to the supplied
pump bracket with the supplied 5/16" hard-
ware. (See Fig. 10-c.)
C. Unscrew the three nuts securing the small
computer style box on the driver’s side fire-
wall. (See Fig. 10-d.)
D. Take the supplied 1/2" I.D. x 90° molded hose
and cut one end short. (See Fig. 10-c.) Slide
the cut end of the molded hose on the barber
end of the vacuum pump that was inserted
into the grommet in the brake booster.
Connect the 1/2" x 19" length of hose to the
90° molded elbow with a 1/2" hose mender.
Secure the pump/bracket assembly to the
three studs using the same three nuts

NOTE: When relocating brake lines, be sure that the brake
lines are clear of the steering column. Tie-wrap the
lines out of the way if necessary.
NOTE: For ease of installation, it may be easiest to
remove the driver’s side hood support and the
plastic electrical center cover.
F. Unbolt the bracket holding the lower brake
line assembly to the brake booster/master
cylinder attachment. (See Fig. 10-a.)
G. Attach the supplied drop bracket to the origi-
nal bracket securing the brake lines with the
supplied 5/16" hardware. With the new brack-
et added, push down the brake lines and
attach the new assembly to the original two
studs. This will drop the brake lines making
clearance for the inlet tube. (See Fig. 10-b.)
H. Using the supplied 1/2" x 22" hose and 1/2"
hose mender connect the existing hose run-
ning from the manifold to the down-turned
barb on the vacuum pump. Cut hose lengths
for best fit.

NOTE: It is important that the plug running to the pump is
properly connected. Failure to do so will cause the
throttle not to respond.
