17. FUEL PUMP VOLTAGE BOOSTER INSTALLATION
Fig. 17-a
A. The voltage booster will be installed next to
the fuse/relay center. Use the supplied adhe-
sive backed Velcro to mount it as shown.
(See Fig. 17-a.)
B. Use the supplied 10 gauge wire to lengthen
the power wire (orange or red with inline
fuse) to terminal #87 on the water pump
relay. Splice the water pump power wire into
one of the connectors before crimping.
(Terminal #87 should now be supplying power
to the water pump and the voltage booster
when the vehicle is running or for a couple of
seconds after the key is turned “on”.)
C. Ground the booster in the same location used
for the water pump ground.
D. Run the supplied red wire from the voltage
booster power supply wire (red-no fuse) down
the passenger side frame rail to the main fuel
tank. Use the supplied tie-wraps to secure
the wires away from heat and moving parts.
E. Cut the fuel pump power lead (larger gray
wire on the right side of the fuel pump plug
as viewed from the end with the plastic tab
on top). Connect the voltage booster power
lead to the pump side of the factory fuel
pump power lead.
F. Run the red and black shielded wires over
near the brake master cylinder and connect
to the supplied pressure switch.
G. Using the supplied hose and TEE, connect
the pressure sensor on the voltage booster to
the bypass valve line installed in section
15-d.
H. Turn the controller knob to “max” and secure
out of the way.
(Tuner or H.O. kits only - All others Proceed to Step 18)
NOTE: The purpose of the voltage booster is to raise the
voltage to the factory fuel pump when the vehicle is
in boost. This will raise the fuel flow in order to main-
tain fuel pressure on high horsepower applications.
Use the instructions supplied with the voltage boost-
er to supplement the following:
NOTE: Fuel pump or voltage booster components are not
included in the Vortech systems. These are accesso-
ries that can be purchased separately.
