GENERAL INFORMATIONThe information in this manual applies to a series of GPI pumps:• M-150S 12-volt, available with automatic or manualnozzle• M-180S High flow pump available with automatic ormanual nozzle• M-240S 24-volt pump with manual nozzleThe information applies to all models, except where noted.This manual will assist you in operating and maintaining your12-volt or 24-volt fuel pump. It furnishes information whichwill help you achieve years of dependable performance andtrouble-free operation.Please take a few moments to read through this manualbefore installing and operating your pump. If you have problemswith the pump, refer to the Maintenance and TroubleshootingSections.If you need assistance, contact the dealer from whom youreceived your pump. If you need further assistance, pleasecall the factory.How to Use this ManualMost information in this manual applies to both 12-volt and 24-volt electric gear pumps with an automatic or manual nozzle.This symbol is used throughout this manualto call your attention to safety messages.Warnings alert you to the potential for personal injury.Cautions call attention to practices or procedures which maycause damage to your equipment.Notes give you information that can improve efficiency ofoperations.It is your responsibility to:• know and follow applicable national, state, and local safetycodes pertaining to installing and operating electricalequipment for use with flammable liquids.• know and follow all safety precautions when handlingpetroleum fuels.• insure that all equipment operators have access to adequateinstructions concerning safe operating and maintenanceprocedures.Safety InstructionsThis is a safe product, designed and manufactured to meetthe high safety standards of Underwriters Laboratories (Motorfor Hazardous Locations) and the Canadian StandardsAssociation (CSA). It is designed to safely handle fuel productsand, if installed, operated, and maintained correctly, willgive years of dependable service.Important InformationTo insure safe operation, all fuel transfer systems must beproperly grounded.Proper grounding means a continuous metal-to-metal contactfrom one component to the next, including tank, bung,pump, meter, filter, hose, and nozzle. Care should be takento insure proper grounding during initial installation and afterany service or repair procedures.All factory-supplied accessories and components assureproper grounding.Here is a list of major warnings and cautions that are giventhroughout this manual. Please take a moment to review themnow for your future safety.1. To prevent physical injury, observe precautions againstfire or explosion when dispensing fuel. Do not operate thesystem in the presence of any source of ignition includingrunning or hot engines, lighted cigarettes, or gas or electricheaters.2. Observe precautions against electrical shock when operatingthe system. Serious or fatal shock can result fromoperating electrical equipment in damp or wet locations.3. Avoid prolonged skin contact with petroleum fuels. Useprotective goggles, gloves, and aprons in case of splashingor spills. Change saturated clothing and wash skinpromptly with soap and water.4. This pump is designed for use only with gasoline, kerosene,and diesel fuel. Do not use this pump for dispensingany fluids other than those for which it was designed. Todo so may damage pump components and will void thewarranty.5. Do not leave the system running without fluids. “Dryrunning” can damage the pump. If the system fails todeliver fuel after 15 to 20 seconds, turn the system off andrefer to the Troubleshooting Section.6. Inspect external pump wiring regularly to make sure it iscorrectly attached to the battery. To avoid electrical shock,use extra care when connecting the pump to power.7. Do not pump the tank completely dry, as contaminantsfrom the bottom of the tank may enter the pump.8. To avoid pump damage, do not run the pump for morethan 10 minutes with the nozzle closed.9. The duty cycle of this pump is 30 minutes ON and 30minutes OFF. Allow the pump to cool for 30 minutes.10. Observe precautions against electrical shock when servicingthe pump. Always disconnect power before repairingor servicing. Never apply electrical power to thesystem when any of the coverplates are removed.11. If using solvent to clean pump components or tank, observethe solvent manufacturer’s recommendations forsafe use and disposal.Damage InspectionUpon receipt of your system, inspect all parts and components.Remove protective caps and plugs, as needed, for athorough inspection.If any items are damaged or missing, please contact yourdealer or distributor.2
INSTALLATIONBefore installation, wrap all threaded fuel connections withthree to four turns of Teflon ® tape or a pipe thread sealantapproved for use with petroleum fuels.Review the Important Information on page 1 before proceeding.PrimingThis pump is designed to self-prime with dry gears. Expectsuction lift as follows:Manual Nozzle: 5.5 feet (1.7 m) with diesel6.7 feet (2.1 m) with gasolineAutomatic Nozzle: 4.8 feet (1.5 m) with diesel5.8 feet (1.8 m) with gasolineIf your installation requires a greater distance from the lowestfuel level to the pump, the pump may not prime until the gearsare coated with fluid.To coat the gears, remove the plug on the top of the pump (asdetailed in Figure 8) and pour a small quantity of motor oil intothe gear cavity. Replace the plug, turn the pump on, and openthe nozzle.A UL Listed foot valve with pressure relief will be required tomaintain prime.Install Bung Adapter and Suction PipeBefore installation, wrap all threaded fuel connections withthree to four turns of Teflon ® tape or a pipe thread sealantapproved for use with petroleum fuels.1. Tighten the bung adapter snugly on the fuel tank.2. Place the union ring gasket into the inlet fitting on thebottom of the pump.3. Thread the suction pipe into the inlet fitting and tightenuntil snug.Install Pump on Tank1. Clean the tank interior of all dirt and foreign material.2. Extend the suction pipe to its full length and insert into thetank opening. (Figure 1)3. Place the pump on the bung adapter and tighten theunion ring securely with a pipe wrench. Make sure theunion ring is not cross-threaded.NOTE: To prevent pressure buildup and possible fuel leaksthrough the nozzle, make sure the tank is vented. A ventcap rated at 3 psi or less is recommended.Install Electrical ConnectionsPumps designed for a 12-volt power source should be connectedto a 12-volt battery. Pumps designed for a 24-voltpower source should be connected to a 24-volt battery. Donot attempt to install on a 115-volt power source.To install power cord:1. Remove the electrical coverplate from the pump housing.(Figure 2)Figure 22. Models M-150S and M-180S: Adjust power cord todesired length. Strip 3 to 4 inches (7.5 to 10 cm) ofouter insulation from the power cord.Model M-240S only: Adjust power cord to desiredlength. Strip 3 to 4 inches (7.5 to 10 cm) of outerinsulation from the power cord end without the fuse.3. Slide the strain relief grip over the end of the power cord.The threaded end of the strain relief grip must face thepower cord end. (Figure 3)Figure 3Figure 14. Strip 1/2 inch (1.3 cm) of insulation from the red and blackpower cord wires.The suction pipe will adjust to the length needed to reston the tank bottom.5. Insert the power cord through the power cord inlet on theback of the pump. (Figure 4) Using wire nuts, connect theblack wire of the power cord to the black wire in theelectrical cavity. Connect the red wires in the samemanner.6. Position wires inside the electrical cavity until flush. Insertthe strain relief into the back of pump and tighten. Tightenthe strain relief grip securely.3
