Sending unit wiring 68 camaro
I got this camaro a few months back and the fuel gauge did not work. I started Removing items to do mini tubs and dropped the tank to see no wires connected. The previous owner said it had no sending unit but it sertantly does.
It’s currently setup with an external pump so the only thing in the tank is the sending unit, float and pickup. Check out the photos below, not sure how this is to be wired. The tan colored wire near the full tube has a wire nut and was talked up out of the way. This one is supposed to be for the sending unit. There was a black wire that looked like a ground the was talked up out of the way connected to the sending unit only. This one is hard to see in the pic btw. There is a brass piece sticking out of the top of the sending unit on the outside of the tank that is not threaded or anything. Is this something i need to connect to?
Any way to make this work or should i purchas a new one?

According to 1968 Assembly Manual, the tan wire originally had an "L" shape connector on it that pushed on the brass stud of the sending unit. The black wire was grounded to the body near the right front tank strap attachment point.

You should be able to check the rest of the system by grounding the tan wire. I believe the gauge should move to the full position.
