12V DC and 24V DC Wiring Instructions

FR1200 / FR2400 / FR4200 / FR4400 / SD1200 Series DC Transfer Pump
Electrical wiring should be performed ONLY by a licensed electrician in compliance with local, state, and national electrical
codes (NEC/ANSI/NFPA 30, NFPA 30A, and NFPA 70) as appropriate to the intended use of the pump. 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 personal injury or death.
Do not connect the positive or negative power to the green ground/earth screw or ground/earth wire as this could
cause a fire.
Do not attempt to power the pump from vehicle wiring smaller than 12 AWG such as the cigarette lighter wire because
these thin wires could overheat and cause a fire.
For wiring up to upfitter switches, please contact Tuthill Customer Service at 1-800-634-2695 (M-F, 8am-6pm EST/EDT).
Fill-Rite DC fuel pumps are designed to operate at the rated nameplate voltage. Series FR1200, FR4200, and SD1200
are rated for 12V DC while FR2400 and FR4400 are rated for 24V DC. Regardless of how supply line power is provided
(i.e. via a battery or hard line), Tuthill requires the circuit contain a fuse to prevent against electrical shorts. For 12V
DC, a 30 amp fuse is necessary while for the 24V DC circuit, a 20 amp fuse.
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 the supplied 18' 12 AWG power cable*, refer to local, state, and national electrical codes
to ensure the wire is of the correct size for this application.

Electrical bonding is the process of connecting metallic parts such as a fuel storage tank or transfer pump which may
be exposed to electrical faults to a grounding conductor to ensure a low-resistance path to the ground. Bonding also
provides a path for static electricity and induced voltages to drain out through the grounding path. The most common
way to bond is with a copper wire.
If the intention is to operate either a 12V or 24V DC fuel transfer pump from a power supply other than a vehicle battery
system, please contact Tuthill Customer Service at 1-800-634-2695 (M-F, 8am-6pm EST/EDT).
