Threaded rigid conduit, sealed fittings, and conductor seal should be used where applicable.
The pump must be properly grounded. Improper installation or use of this pump can result in serious bodily injury or death!

WARNING! To ensure the safe and proper operation of your equipment, it is critical to read and adhere to all of the following safety warnings and precautions. Improper installation or use of this product can cause serious bodily injury or death!

• NEVER smoke near the pump, or use the pump near open flames when pumping a flammable liquid! Fire can result!
• A filter should be used on the pump outlet to ensure no foreign material is transferred to the fuel tank.
• Threaded pipe joints and connections must be sealed with the appropriate sealant or sealant tape to minimize the possibility of leaks.
• Storage tanks must be securely anchored to prevent shifting or tipping when full or empty.
• To minimize static electricity build-up, use only static wire conductive hose when pumping flammable fluids, and keep the fill nozzle in contact with the container being filled during the filling process.
• The pump motor is equipped with thermal overload protection; if overheated, the motor will shut off to prevent damage to the windings.

WARNING! This product shall not be used to transfer fluids into any type of aircraft.

WARNING! This product is not suited for use with fluids intended for human consumption or fluids containing water.

INSTALLATION

16GMP fuel transfer pump is designed to be mounted on a skid tank using the threaded inlet flange supplied with the pump. Your pump features an integral bypass valve to recirculate the fluid when the pump is operating with the nozzle closed.

WARNING! This product is not suited for use with fluids intended for human consumption or fluids containing water.

CAUTION! Do not use additional check valves or foot valves unless they have a proper pressure relief valve built into them. Note that additional check valves will reduce the rate of flow.

CAUTION! A pressure-retaining fill cap can be used to reduce fuel loss through evaporation, but note that it will reduce the flow rate.

CAUTION! Threaded pipe joints and connections must be sealed with the appropriate sealant or sealant tape to prevent the possibility of leaks.

WARNING! 16GMP fuel transfer pumps are designed for use with stationary and mobile tank applications. While DC-powered units are excellent choices for mobile applications, anchoring the tank to which the pump is mounted is paramount to ensure no movement in transit.
Failure to secure the tank to the vehicle can cause uncontrolled movement, resulting in damage, injury, and potential fire.

Typical Skid Tank Installation

The pump mounts to the bung of a skid tank by way of the inlet flange. The suction tube threads into the bottom of the inlet flange and must extend to a length that positions it at least 3” from the bottom of the tank. The skid tank should be equipped with a vent cap.

Materials:

• 1” telescoping suction pipe extended to a length that will extend to within 3” of the bottom of the tank when screwed into the tank adapter with the tank adapter screwed into the tank flange (see SKID TANK INSTALLATION diagram).
• Threaded pipe joint sealant appropriate for the application.

Installation Procedure:

1. Thread the 1” pipe into the tank adapter. Seal threads liquid tight with appropriate sealant. (Figure 1)

2. Screw the inlet flange (with suction pipe) into the tank bung; seal threads liquid tight with appropriate thread sealant (Figure 2).

3. Mount the pump on the adapter, making sure the seal and screen are installed as shown. (Figure 3).

ELECTRICAL WIRING

CAUTION! DC-powered pumps are designed to operate on either 12 or 24 VDC (depending on the model). Where applicable, use the supplied battery cable to supply power to the pump from a 12 or 24-VDC battery. A 30 amp fuse (20 amp fuse on 24 VDC motors) should be installed on the battery cable to protect the wire in case of an electrical short.

CAUTION! Voltage drop-in wiring varies depending on the distance from the battery to the pump and the gauge of the wire used. If the distance is greater than 20’, refer to national, international, or local electrical codes to ensure the wire is of the correct size for this application.

Instructions Before Proceeding With DC Wiring

The pump needs to be electrically bonded to the supply tank or vehicle frame. To electrically bond the pump, remove the green bonding screw located next to the junction box cover. Insert this screw through an eyelet of furnished green bonding wire assembly and refasten it securely to the pump. The other end of the wire is to be stripped of insulation, and the bare wire securely bonded to the vehicle / trailer frame or skid tank.

WARNING! Do not connect the positive or negative power to the green screw or wire, as this could cause a fire.

Wiring Instructions

1. Remove the pump’s electrical junction box cover and straighten the 2 wires to make the stripped wire ends accessible outside of the junction box.
2. Screw furnished cable connector into NPT* conduit opening in the pump junction box.
3. Strip 6 inches of the outer covering from one end of the furnished electrical cable, being careful not to damage the black and red wire insulation.
4. Loosen the cable connector nut and pass the stripped end of the furnished cable through the cable connector. Tighten the cable connector nut.
5. Strip 1⁄2 inch of the insulation from the ends of the red and black cable wires. Using the furnished wire nuts, connect these wires to the pump wires matching the colors. Be sure no bare wire is exposed.
6. Fold wires into the junction box and replace the cover making sure the gasket is in place. Make sure all screws are seated, so there is no space between the cover and the junction box.

Wiring To A Vehicle Electrical System

1. Pass the electrical wires to the source of the vehicle power system, supporting the wires as necessary and protecting them from sharp edges, heat, and anything that could damage the wires.

2. To determine if the vehicle’s electrical system is negative (-) or positive (+) ground, check the battery marking of the terminal that is wired to the vehicle frame or motor block. The red wire from the pump will connect to the positive battery post, and the black wire from the pump will connect to the negative battery post.

3. Attach one end of the fuse holder to the end of the ungrounded wire.
   Make a solid electrical connection with the other end of the fuse holder to the ungrounded side of the battery, as close to the battery as possible. Make a solid electrical connection to the grounded side of the  battery with the remaining wire. The battery terminal or the end of thebattery cable is recommended.

4. Check all connections to make sure they are connected per instructions and all electrical codes. Install the 30 amp fuse (20 amp fuse in 24 VDC installations) in the fuse holder. The installation is now complete.

WARNING! Do not attempt to power the pump from vehicle wiring smaller than 12 gage, such as the cigarette lighter wire, because these thin wires could overheat and cause a fire.

DC Wiring (cont’d)
For Skid Mounted Tanks

1. Pass the electrical wires to the power source, supporting the wires as necessary and protecting them from sharp edges, heat, and anything that could damage the wires.
2. Attach one end of the fuse holder to the red pump wire, as close to the battery /power source as possible. Make a solid electrical connection to the positive terminal of the power source with the other end of the fuse holder. Make a solid connection with the black pump wire to the negative terminal of the power source.
3. Check all connections to make sure they are connected per instructions and all electrical codes. Install the 30 amp fuse (20 amp fuse in 24 VDC installations) in the fuse holder. The installation is now complete.
