Product Manual

If you require a greater initial prime height, coat the gears with
fluid by removing the plug on the top of the pump and pour
a small quantity of motor oil into the gear cavity. Replace the
plug and try again. A foot valve with pressure relief may be
needed to maintain prime.
Make sure all threaded fuel connections are wrapped with three
to four turns of thread tape or a pipe thread sealant approved
for use with petroleum fuels.
Install Bung Adapter and Suction Pipe
• Tighten the bung adapter snugly into the fuel tank.
• Place the union ring gasket into the inlet fitting on the
bottom of the pump.
• Thread the suction pipe into the inlet fitting and tighten
until snug.
Install Pump on Tank
• Clean the tank interior of all dirt and foreign material.
• Extend the suction pipe to its full length and insert into
the tank opening. (Figure 1)
The suction pipe will
adjust to the length
needed to rest on the
tank bottom.
• Place the pump on the bung adapter and tighten the union
ring securely with a pipe wrench. Make sure the union ring
is not cross-threaded.
• To prevent pressure buildup and possible fuel leaks through
the nozzle, 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.
Models M-150S and M-180S should be connected to a 12-volt
DC power source.
Model M-240S should be connected to a 24-volt DC power
source.
Do not attempt connection of any pump to a 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.
(Figure 2)
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 inch (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
wires. (Figure 3)
Insert the power cord through the 1/2 inch NPT connection on
the back of the pump. (Figure 4) Using wire nuts, connect the
black wire to the black wire and the red wire to the red in the
pump’s electrical cavity. Position the wires inside the electrical
cavity and tighten the strain relief grip securely. Make sure sur-
faces are clean. Install the coverplate and tighten securely.

Carefully route the power cord to the battery, protecting
the power cord from hot surfaces, sharp edges or any-
thing 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 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 instructions could result in death,
serious injury or loss of equipment due to short circuit,
fire or explosion.
