Fuel tank sending unit

I knew I had this photo somewhere.... bottom item (shiny) is a new sender from Jeg's or Summit (I forget) — exactly the same as the PlumKrazy part above (and much cheaper). Top is the factory A-body sender — completely different.

I've never seen this sender that you are showing as an original type. Only the one with the pivot in the middle. Even original ones I've removed are that middle pivot style. At least on the 74-76 models I've worked on.

If it really is non linear, then this could be a big improvement.

I would have to say it is. Using it in my daily with the factory gauge, it's not amazingly accurate, but empty is now pretty close to empty, and a half tank reading takes close to a half tank worth of fuel. Whereas with other senders I've tried across other cars I've owned, every time, empty would actually be half tank. This one is pretty darn close to correct. I'm sure the gauge isn't exactly spot on either, but it's definitely close enough.

Ummm just to clear this up, "EVERY American made A body" did NOT come with the same cluster, so I have no clue what you're talking about.

Random picture from the internet, but this is the only cluster in the A body that I am aware of from I believe 1970-1976. If there is another, I've never seen one. I've had several 74s, a 75, and 76, and scrounged parts from several in junkyards going back to 72. Swingers, Dusters, Valiants, I've only ever seen this in them. Even in videos and pictures. If there was a different one available, I'm curious as to what it is.
