GENERAL INFORMATION
The purpose of this manual is to assist you in installing,
operating and maintaining your GPRO™ pump. This
manual covers 12-volt DC model PRO20-012.
Model Components
PRO20-012AD: Includes pump, hose and automatic
diesel nozzle.
PRO20-012MD: Includes pump, hose and manual diesel
nozzle.
PRO20-012PO: Includes pump only.
NOTE: Sufxes MD, AD and PO are for ordering purposes
only. Constructions described above are covered as
alternate constructions under the Part No. PRO20
UL Listing.
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 automo-
tive 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.
SAFETY INSTRUCTIONS
The following safety alert symbols are used in this
manual.
DANGER
DANGER indicates a hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING
WARNING indicates a hazardous
situation which, if not avoided,
could result in death or serious
injury.
CAUTION
CAUTION indicates a hazardous
situation which, if not avoided,
may result in minor or moderate
injury.
It is your responsibility to:
• Know and follow applicable national, state and local
safety codes pertaining to installing and operating
electrical equipment for use with ammable liquids.
• 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 continu-
ous 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 oper-
ating 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 splash-
ing 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, ob-
serve the solvent manufacturer’s recommendations for
safe use and disposal.
INSTALLATION
Install Suction Pipe
Your pump is designed to mount directly to a standard
2 in. 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.
