If the ground Stumpy mentions isn't the issue, then you have an open wire between the sender and the gauge. BTW, two hose clamps and a length of wire will substitute for the strap linked.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Make sure the part inside the connector is contacting good.Ive seen them spread and or get corroded and not work.I always crimp them a but when I install the wire to the sender.I also run a ground from the battery to the sender to test them.Ive also seen where someone has tried to ground the sender on the hose instead of the nipple.I like to run a wire to the sender and ground it to the body.Its better than the factory clip.That and if the fuel line to the front isnt grounded the unit wont be grounded.Rocky

sending unit is out of the ca. I am manually raising the float. at the same time grounding it. I actually use a test light to make sure the unit is grounded.
OK silly question, Out of the car, can you make the gauge work with the sending unit by grounding it, hooking it up and manually moving the float arm??

No I can not get the gauge with sender out of the car.

It has to be something stupidly simple
Grounds as in electrical. Some sending units/ rheostats want to be "wet" IE: think fuel/vapors. BUT be careful as a errant spark can send on to the local emergency room.
If the gauge and wiring are good which they appear to be from your posts, the problem is with the sending unit, grounds to it, or the connection to the unit. PERIOD!!! ground connections will send you to a mental institution, Nuff said!!! I suspect you think you have a good ground but the sending unit doesn't agree be careful
Thanks for your input. I feel the same as a bad ground. So I attached a ground wire from the sender to the frame plus I used a jumper cables from the battery to the sender.
I did not know about being wet.
I did get the gauge (with sender) to move just above empty and that was as far as it went. I am leaning towards the ground because the rheostat was a little warm, just can't think of a better way to ground it short of soldering it.
Plus I double checked the gauge by grounding it and it did go to full

You might submerge it in a large container of water & with some jumper wires run 12V to the input nipple & ground the case & see how it acts submerged. Hold it at the same angle it would be in the tank
