Sending Units

0-90 Ohms | 0-Empty | 90-Full

RCI sending units will work with most GM factory gauges and all aftermarket
gauges with 0-90 Ohm setup. The center post wires directly to the gauge and
you must ground the sending unit from one of the outside bolts of the sending
unit to your frame.

(Always make sure your fuel cell is properly grounded and vented)
