Brandon Rhoads · 09-14-2009, 02:57 PM

Im in the process of putting some auto meter guages in my dash and I wana get a fuel guage for it but I need to know the ohm reading for empty and full tank. I know there are guys that have done this but don't mention what Im looking for. what I got so far is 73 ohm for empty and 10ohm for full. The guy said he isn't sure about it. So any info woud be helpfull

What are you putting it into? I know the CJ's are 73 empty and 8-12 full. I put this one in my CJ with a 20 gal factory tank.

It works, E is 5 gal, 1/4 is 10 gal. Leaving the top of the tank a bit "small" on the gauge but I know what it reads so I'm good.

That same ohm gauge I posted is for most Chrysler applications too, so thats the ohm range gauge you need.

works for me. I was looking at the ultra-lite # ATM-4315 . Its in the ohm range I need. Hope its not a pain in the ass to install

I just hooked up the lead from the sending unit from the stock gauge to the new one, and made sure it had a good ground. I did a custom dash though so I was planning for it.

But his is a TJ, isn't he going to have the little circuit board on the back of the guages? I know my YJ did. So I had to follow the wiring to where it contacts the circuit board, and follow the specific circuit.

But that's just a guess, so don't quote me. I haven't tore the guage cluster out of my TJ yet...

yeah there is a circut board. I should be able to tap in where the sending unit is right?
