XJ fuel gauge

Not really MJ related, but to technical for the pub I feel.

 

Can an XJ fuel gauge be setup to run stand alone? Can I just yank it out the cluster and apply power/grd/signal and get it to work?

 

My brother and I have finally gotten around to working on our j10 and would like to put in a fuel tank and functioning gauge. We had the thought of getting a Cherokee fuel tank, sending unit and gauge since they are easy to come by and cheap. But I don't know if it can be removed from the cluster and operated as a stand-alone gauge.

Looks like it can. The direction of power feed for the fuel sender is +12 volts to the gauge, then from the gauge to the sender, and from the sender to ground.

Yes, it will.

 

As a cleaner option the standard old GM is a very similar resistance range (0-99 ohms vs 0-88 ohms) and you can get an aftermarket one of those for very little money...  It just might not peg right full with the tank full, but it will be very close as most gauges are calibrated to show past the full line when absolutely full.
