AutoMeter offers a universal sender under model number 3262. It operates from 240 ohms at empty and 33 ohms at full. It is adjustable from 5” to 24” tank depths. It uses a 5 bolt mounting flange. In most cases, it may be necessary to cut a new hole in the top of the tank to use this sender. It does not replace spin lock or ring type factory sending units.
Another option is if you are using full sweep programmable fuel level gauges. (not the standard short sweep version). The full sweep programmable unit may be custom calibrated to operate with nearly any variable resistance to ground sender that has a range between 0 and 270 ohms.
