INSTALLATION
Install Suction Pipe
Your pump is designed to mount directly to a standard 2-inch
NPT tank fitting. For the suction pipe, a 1-inch galvanized steel
pipe cut to length and threaded on one end may be used. Suc-
tion pipe should extend to within 3 inches of tank bottom. 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.
Install Pump on Tank
• Clean the tank interior of all dirt and foreign material.
• Place the pump with suction pipe installed on the tank
fitting and tighten securely. Make sure the pump is not
cross-threaded.
• To prevent pressure build-up 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-3025 and M-3025CS must be connected to a 12-volt
DC power source only.
Models M-3425 and M-3425CS must be connected to a 24-volt
power source only.
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.

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 2)

Insert the power cord through the 3/4 inch NPT connection on
the bottom of the pump. Attach ground wire (green) using green
ground screw located inside the electrical cavity. (Figure 3)
Figure 3
Using wire nuts, connect the black wire to the black wire and
the white (or red) wire to the white (or red) wire 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.
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 fuse is provided to protect the power cord and motor. Install
fuse in the white (or 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 instruction could result in death, seri-
ous injury or loss of equipment due to short circuit, fire or
explosion.
