Hey AK,
I am a loyal member and have helped folks when ever I could with detailed hard to answer type stuff and now I am stuck. I can't seem to locate the answer I need, I have tried to hunt down the answer but come up short. I installed the Stillen Supercharge about 2 years ago and have installed several after market gauges.

My last gauge I want to install is a "FUEL LEVEL GAUGE" but you probably know fuel gauges need specific ohm values at EMPTY and at FULL. Those resistance values are provided (I believe) by the Fuel Tanks Sending unit.

I am interested in installing a Fuel Level Gauge (ideally with a white face and a red needle) Autometer has several in this flavor but all come with specific Fuel Tank "EMPTY Ohm Value" and "FULL Ohm Value" requirements for the gauge to be accurate, but I don't know which one would would for my 2011 370Z?

I think this is what I need to know?
1. Need to know what the "Empty State" and "Full State" (Ohm values) are that the sender is sending out because that is what most gauges use to sense off of and display the value? ie: 20 ohms when tank is empty increasing to 50 ohms when tank is full.
2. Where do I locate the wires for the Fuel Level Senders Output so I can tap into them to connect the after market Fuel Level gauge?

If there was a DIY on this forum I would say just point me to that.
Thanks AK...

Kind Regards,
James aka: 370Z1
