GPI G8 Portable Fuel Transfer Pump User Manual

G8 Portable Fuel Transfer Pump

GENERAL INFORMATION

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 fluids 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 12-volt DC automotive electrical system. The pump is designed to operate with 12-volts DC 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 vehicle charging system that will affect system voltage.
_ NOTE: This pump is not intended for _use with an automatic nozzle.

WARNING: This product shall not be used for pumping fuel or other liquids into aircraft.

_ NOTE: An automatic bypass valve _prevents pressure build up when the pump is on with the nozzle closed. To avoid motor damage, do not run the pump more than 5 minutes with the nozzle closed.

The rated duty cycle of this pump is 15 minutes ON and 30 minutes OFF. Allow the pump to cool for 30 minutes.
Do not leave the system running without fluids. “Dry running” can damage the pump. If the system fails to deliver fuel after 15 to 20 seconds, turn the system off and refer to the Troubleshooting Section.
Do not pump the tank completely dry, as contaminants from the bottom of the tank may enter the pump. IMPORTANT! DO NOT RETURN THIS PRODUCT TO THE STORE. Please contact Great Plains Industries, Inc. before returning any product. If you are missing parts, or experience problems with your installation, contact our Customer Support Department. We will be happy to assist you. Call 800-835-0113 or 316-686-7361 or

SAFETY INFORMATION

Observe all safety precautions concerning safe handling of petroleum fuels.
For your safety, please take a moment to review the warnings throughout this manual.
To prevent physical injury, observe precautions against fire 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 in good condition. 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.

INSTALLATION & OPERATION

Pump Installation

Make sure all threaded fuel connections are wrapped with three to four turns of the supplied thread tape.
Make sure supply tank or container is vented. A vent cap rated at 3 psi or less is recommended.
_ NOTE: These components have _not been evaluated as part of the UL Listed Equipment and are not intended for use in a Hazardous (Classified) Location.

Install Inlet Hose and Strainer

Wrap the threads of one end of the inlet hose 3 or 4 times with thread tape (supplied). Install hose end into inlet side of pump (see Figure 1) and tighten. Wrap threads on other end of hose 3 or 4 times with thread tape (supplied). Install metal strainer and tighten. To avoid damage to pump from dirt and debris, do not operate pump without strainer.

Install Outlet Hose and Nozzle

Wrap the threads of one end of the outlet hose 3 or 4 times with thread tape (supplied). Install hose into outlet side of pump (see Figure 1) and tighten. Wrap threads on other end of hose 3 or 4 times with thread tape (supplied). Install manual nozzle and tighten. To minimize static electricity build up and possible explosion, use only static wire conductive hose when pumping

flammable fluids. Keep the fill nozzle in constant contact with the container being filled during the filling process. Sparks or static discharge will cause explosions.

Install Ground Wire

An external ground wire is provided for use where required. GPI strongly recommends grounding your pump prior to use. To attach the ground wire, remove one of the 1/4-20 x 1/2” hex head screws and install the ground wire ring terminal (see Figure 2). Reinstall hex head screw and tighten securely. Attach the alligator clamp end of the ground wire to the earth or chassis ground of the vehicle your are filling.

Connect to Power Source

NOTE: This pump is designed to operate on a typical 12-volt DC automotive electrical system.
DO NOT attempt to connect to a 24- volt or 115-volt electrical system.
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 20-amp inline fuse is supplied on the power cord’s red wire to protect the motor and power cord. Connect the red wire with red clamp to the positive (ungrounded) side of the power source. Connect black wire with black clamp to the negative (grounded) side of the power source.
_ NOTE: Power cord components, _such as the switch and fuse, have not been evaluated as part of the U. L. Listed equipment.

_ 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: This pump is not intended for use in CLASS I,_ DIVISION I locations.

Dispense Fuel

First, insert the nozzle into the receiving tank, and then turn on the pump with the inline switch (see Figure 3). Squeeze the nozzle handle to start fuel flow. When done, release the nozzle handle and turn the pump off at the switch. Always insert nozzle into tank before turning pump on.
This pump is designed to be selfpriming. If fuel is not delivered within 15 to 20 seconds, turn the pump off and refer to the Troubleshooting Section of this manual.
An automatic bypass valve prevents pressure build up when the pump is on with the nozzle closed. To avoid pump damage, do not run the pump more than 5 minutes with the nozzle closed.
After running the pump for a maximum of 15 minutes, allow it to cool for 30 minutes.
When finished refueling, make sure the pump is turned off at the switch and disconnect the power cord from the 12-volt power source.

MAINTENANCE

This pump is designed for minimum maintenance. Motor bearings are sealed and require no lubrication. Inspect the pump and components regularly for fuel leaks and make sure the hose and power cord are in good condition. Keep the pump exterior clean to help identify leaks.
Do not use this pump for water, chemicals or herbicides. Dispensing any fluid other than that listed in this manual will damage the pump. Use of the pump with unauthorized fluids will void the warranty.
A kit containing O-rings, motor shaft seal and gears is available for this pump. To order replacement kit, contact GPI and ask for part number #147500-01 Gears and Seals
Overhaul Kit.
