GENERAL INFORMATION
The purpose of this manual is to assist you in installing,
operating and maintaining your GPI pump. This manual
covers 12-volt DC model M-3020.
M-3020 must be connected to a 12-volt DC power source
only.
Do not attempt connection of any pump to a 115-volt AC
or 230-volt AC power source.
An automatic bypass valve prevents pressure build
up when the pump is on with the nozzle closed. To
avoid damage, do not run the pump more than 10
minutes with the nozzle closed.
The duty cycle of this pump is 30 minutes ON and 30
minutes OFF. Allow the pump to cool for 30 minutes.
This pump is designed for use only with gasoline (up
to 15% alcohol blends such as E15), diesel fuel (up to
20% biodiesel blends such as B20) and kerosene. Do
not use this pump for dispensing any uids other than
those for which it was designed. To do so may damage
pump components and will void the warranty.
This pump is designed to operate on a typical DC automotive electrical system. The pump is designed to operate
with the appropriate DC voltage at the motor leads and
the ratings are determined at this voltage. Performance
may vary due to length of power cord, battery condition
or output from the vehicle charging system that will affect
system voltage.
Do not leave the system running with uids. “Dry running”
can damage the pump.
Do not pump the tank completely dry, as contaminants
from the bottom of the tank may enter the pump.
• Know and follow all safety precautions when handling
petroleum fuels.
• Ensure that all equipment operators have access to
adequate instructions concerning safe operating and
maintenance procedures.
Observe all safety precautions concerning safe handling
of petroleum fuels.
To ensure safe operation, all fuel transfer systems must
be properly grounded. Proper grounding means a continuous metal-to-metal contact from one component to the
next, including tank, bung, pump, meter, lter, hose and
nozzle. Care should be taken to ensure proper grounding
during initial installation and after any service or repair
procedures. For your safety, please take a moment to
review the warnings below.
To prevent physical injury, observe precautions against
re or explosion when dispensing fuel. Do not operate
the system in the presence of any source of ignition
including running or hot engines, lighted cigarettes, or
gas or electric heaters.
Observe precautions against electrical shock when operating the system. Serious or fatal shock can result from
operating electrical equipment in damp or wet locations.
Inspect external pump wiring regularly to make sure it is
correctly attached to the battery. To avoid electrical shock,
use extra care when connecting the pump to power.
Avoid prolonged skin contact with petroleum fuels. Use
protective goggles, gloves and aprons in case of splashing or spills. Change saturated clothing and wash skin
promptly with soap and water.
Observe precautions against electrical shock when
servicing the pump. Always disconnect power before
repairing or servicing. Never apply electrical power to
the system when any of the coverplates are removed.
If using solvent to clean pump components or tank, observe the solvent manufacturer’s recommendations for
safe use and disposal.

DANGER indicates a hazardous
situation which, if not avoided, will
result in serious injury or death.
WARNING indicates a hazardous
situation which, if not avoided,
could result in serious injury or
death.
CAUTION indicates a hazardous
situation which, if not avoided,
may result in minor or moderate
injury.
INSTALLATION
Install Suction Pipe
Your pump is designed to mount directly to a standard
2-inch NPT tank tting. Apply thread tape to the suction
pipe thread and securely tighten the suction pipe to the
pump inlet port.
Make sure any check valve or foot valves used are
equipped with proper pressure relief valves.
Install Pump on Tank
• Clean the tank interior of all dirt and foreign material.
• Place the pump with suction pipe installed on the tank
tting and tighten securely. Make sure the pump is
not cross-threaded.
• To prevent pressure build-up 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: The M-3020 must be connected to a 12-volt
DC power source only.
Do not attempt connection of any pump to a 115-volt
AC or 230-volt AC power source
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 re.
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 depend
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 electrical 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 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 connected per instructions and all electrical codes. The
installation is now complete.
WARNING
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 fuse is provided to protect the power cord and motor. Install
fuse in the white (or red) wire of the power cord as close as
possible 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 the battery.
Failure to follow these instruction could result in death, serious
injury or loss of equipment due to short circuit, re or explosion.
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, rst 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
recommended.
Step 3
For temporary wiring: Connect the red and black power
cords to alligator clamps (not included) (Figure 6).
DANGER
If the pump is to be installed in a Hazardous (Classied) location,
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, re or explosion.
Install Hose and Nozzle
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels.
After sealing the threads, tighten the hose into the pump
outlet and the nozzle on the hose. The nozzle can be
placed in the nozzle holder only when the pump is off.
The nozzle holder allows the pump to be locked when
the nozzle is in place.
OPERATION
Figure 6
ALWAYS FOLLOW SAFETY PRECAUTIONS WHEN
OPERATING THIS EQUIPMENT. REVIEW THE SAFETY
INSTRUCTIONS. Before each use, repair leaks around
seals or connections. Make sure hoses are in good condition and connections are tight. Make sure the work area
is dry. Make sure the pump is properly grounded. Repair
