ASSEMBLY AND OPERATION

NOTE: If you are mounting the utility pump permanently on a surface, make sure the surface is square 

or rectangular only. Do not attempt to mount the utility pump on a rounded surface. (Hardware for 

permanent mounting not included.)

NOTE: Always connect the red power cord on the utility pump to the positive (+) side of the craft’s 12 volt 

DC electrical system. Always connect the black power cord on the utility pump to the negative (-) side of 

the craft’s 12 volt DC electrical system.

1.  The inlet and outlet ports on the pump are both dual threaded with an inside diameter of 3/8 

in. NPT and an outside diameter of 3/4 in. This allows for more versatility in selecting a suction 

hose and discharge hose (not included) with the proper threaded male or female connector. See 

figure 1.

2.  If you are connecting a suction hose having a threaded male connector, wrap about 4 in. of pipe 

seal tape (not included) around the threads of the male connector. Then firmly screw the male 

connector into the threaded female connector of the utility pump. Repeat this process for the 

discharge hose having a threaded male connector. See figure 1.

3.  If you are connecting a suction hose having a threaded female connector, wrap about 4 in. 

of pipe seal tape (not included) around the threads of the male connector of the utility pump. 

Then, firmly screw the female connector of the suction hose onto the threaded male connector 

of the utility pump. Repeat this process for the discharge hose having a threaded female 

connector. See figure 1.

4.  Depending on the make and model of the craft on which the utility pump will be used, there are 

many variations as to connecting the utility pump to the craft’s 12 volt DC electrical system. 

Therefore it is recommended that only a qualified technician perform this procedure.

NOTE: It is highly recommended that a circuit protection device and control switch be used when 

permanently installing this pump.
