Install Suction Pipe
Your pump is designed to mount directly to a standard
2 in. NPT tank fitting. For the suction pipe, a 1 inch
galvanized steel pipe cut to length and threaded on one
end may be used. Suction 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.
PRO25-012 models must be connected to a 12-volt DC
power source only.
PRO25-024 models must be connected to a 24-volt DC
power source only.
DO NOT attempt to connect these pumps 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 1)
F I G U R E 1
Trim the power cord to the desired length. If your power
cord is not pre-stripped, strip 3 inches of outer insulation
from the power cord end. Then strip 1/2 inch 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 2)
F I G U RE 2
Insert the power cord through the 3/4 in. NPT connection
on the bottom of the pump.
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.
Inspect the mating surfaces of the electrical coverplate
and electrical cavity for debris. Clean any debris with
an alcohol wipe. If needed, re-apply a light coating of
Lubriplate® 1242 (or equivalent) white lithium grease
to coverplate perimeter, as shown in Figure 3. Reinstall
electrical coverplate and tighten screws securely to 95-
105 in•lbs (10.7-11.8 N•m).

Apply grease around
perimeter, as shown
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 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, serious
injury or loss of equipment due to short circuit, fire or explosion.
