EZ-8 Fuel Pump

GENERAL INFORMATION

These instructions will help you operate and maintain your pump.
This owner’s manual covers the EZ-8, 12-Volt electric gear pump
with manual nozzle.

Notice: This pump is not intended

to be used with an automatic nozzle.

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.

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.

05/09

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.

SAFETY INSTRUCTIONS

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, filter, 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 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 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.

Rev. D 921803-01

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

This pump is designed to self-prime with dry gears.

Make sure all threaded fuel connections are wrapped with three
to four turns of Teflon
for use with petroleum fuels.

Clean and bond the suction pipe top and bottom as necessary.
Thread the suction pipe into the inlet fitting and tighten snugly.
Trim the suction pipe as necessary to leave approximately 1/2 in.
(1.2 cm) clearance from the bottom of the tank. Clean the tank
interior of all dirt and debris. Insert the suction pipe into the tank
opening. Tighten the pump into the tank opening until snug. Do
not cross thread.

Make sure the tank is vented. A vent cap rated at 3 psi or less is
recommended.

Install Electrical Connections

A grounding connection is provided. It is identified as a green
colored binding head screw in the electrical cavity. Connect these
pumps only to a 12-volt DC power source. Do not attempt connec­tion to a 24-volt DC, 115-volt AC or 230-volt AC power source.

For installation in unclassified areas, the supplied power cord,
fuse and strain relief grip may be used.

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.

To install the power cord, remove the electrical coverplate. If
necessary, trim the power cord to the desired length. Strip 3 to
4 inches (7.5 to 10 cm) of outer insulation from the power cord
end. Then strip 1/2 in. (1.3 cm) of insulation from the power cord
wires. Slide the strain relief grip onto the power cord so that the
threaded end of the strain relief grip faces the stripped power cord
wires. Insert the power cord through the 1/2 inch NPT connection
on the back of the pump. Using wire nuts, connect black wire to
black and red wire to red in the pump’s electrical cavity. Position
the wires inside the electrical cavity and tighten the strain relief
grip securely. Make sure surfaces are clean. Install the coverplate
and tighten securely.

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.

DANGER

If pump is to be installed in a Hazardous (Classified) location,
it must be installed by a licensed electrician and conform to
National F
You as the owner, are responsible for seeing that the installa­tion
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.

F

ailure to follow these wiring instructions may result in death

or serious injury from shock, fire or explosion.

ire Protection Association (NFPA) codes 30 and 70.

and operation of your pump complies with NFPA codes

Install Hose and Nozzle

After sealing 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.

OPERATION

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.

GROUNDED.

Ensure the tank contains enough fuel. Make sure the fuel is not
contaminated with debris. Tighten loose tank lids regularly.

Repair any corroded or damaged wiring before use.

MAKE SURE THE PUMP IS PROPERLY

To Dispense Fuel

Turn on the pump by removing the nozzle from the holder and push­ing up the switch lever. Insert the nozzle into the receiving tank and
squeeze the handle to start fuel flow. When done, release the nozzle
handle, turn the pump off, and return the nozzle to its holder.

This pump is designed to be self-priming. If fuel is not delivered
within 15 to 20 seconds, turn the pump off and refer to priming
information in the Troubleshooting Section.

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.

Auxiliary Temperature-Limiting Device

The motor is provided with an internal auxiliary temperature­limiting device. Excessive motor heat can trip the device. It resets
automatically after the motor has cooled.

MAINTENANCE

WARNING

A 20-amp fuse is provided to protect the motor and power
cord. Install fuse in the red wire of the power cord adjacent
to the battery. Connect the red wire of the fuse to the positive
(ungrounded) side of the battery. Connect black wire to the
negative (grounded) side of the battery.

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.
