Install Pump on Tank
• Clean the tank interior of all dirt and foreign material.
• Extend the suction pipe to its full length and insert into
the tank opening. (Figure 1)

The suction pipe
will adjust to the
length needed to
rest on the tank
bottom.
• Place the pump on the bung adapter and tighten the union
ring securely with a pipe wrench. Make sure the union
ring is not cross-threaded.
• To prevent pressure buildup and possible fuel leaks
through the nozzle, make sure the tank is vented. A vent
cap rated at 3 psi or less is recommended.
Connect to a Power Source
Please consult the Owner’s Manual for your vehicle
before proceeding.
NOTE:
Model M-150S should be connected to a 12-
volt DC power source. Do not attempt installation on
a 24-volt or 115-volt system.
WARNING:
Do not attempt to power the pump from
vehicle wiring smaller than 12 gauge, such as the
cigarette lighter wire, as these thin wires could
overheat and cause a fire.
NOTE:
This pump is pre-wired for installation in
CLASS I, DIVISION 2 locations such as portable fuel
tanks, trailers, etc. Connection to a battery will de-
pend upon the application.
WARNING:
If pump is to be installed in
a CLASS I, DIVISION I location please
contact GPI for the appropriate product.
Verify switch is in OFF position, then route the electri-
cal wires to the source of the vehicle power system.
Be sure to support the wires as necessary and protect
them from sharp edges, heat or anything that could
damage the wires.
Step 1
If the power cord provided is too long cut to desired
length. Carefully strip 3 to 4 inches (7.5 to 10 cm) of
outer insulation from end of power cord.
DO NOT CUT
INNER WIRES
. Next, strip ¼ inch (0.6 cm) of insulation
from the black and red power cord wires.
Step 2
For a negative ground system, first disconnect the
vehicle’s ground wire, and then wire as follows: Insert
one end of the fuse (J) into the wire connector (H) and
crimp. Insert the red power cord wire into the other
end of the wire connector and crimp. Make sure the
fuse is positioned outside of hazardous areas and as
close to the battery as possible. Make a solid electrical
connection to the grounded side of the battery with the
remaining black wire. Connecting directly to the battery
terminal or the end of the battery cable is recommend-
ed.
Step 3
For temporary wiring: Connect the red and black pow-
er cords to alligator clamps (not included) (Figure 6).
Figure 6
Step 4
For permanent wiring:
Connect the red and black power cords to terminal
post rings (not included) (Figure 7).
Figure 7
Step 5
Check all connections to make sure they are connect-
ed per instructions and all electrical codes. The instal-
lation is now complete.
Carefully route the power cord to the battery, protecting the
power cord from hot surfaces, sharp edges or anything that
could damage the power cord, resulting in a short circuit.
A 25 amp fuse is provided to protect the power cord and motor.
Install fuse in the red wire of the power cord as close as pos-
sible to the battery. Connect the red wire of the fuse to the
positive (ungrounded) side of battery. Connect black wire to
the negative (grounded) side of battery.
Failure to follow these instructions could result in death, serious
injury or loss of equipment due to short circuit, fire or explosion.
WARNING
If the pump is to be installed in a Hazardous (Classified) loca
-
tion, it must be installed by a licensed electrician and conform
to National Fire Protection Association (NFPA) codes 30 and 70.
You as the owner, are responsible for seeing that the installation
and operation of your pump complies with NFPA codes as well
as any applicable state and local codes. Rigid conduit must be
used to install wiring. Note that the lead wires are factory-sealed
isolating the motor from the junction box.
Failure to follow these wiring instructions may result in death or
serious injury from shock, fire or explosion.
DANGER
