Before you spend money on another sender see if you can get a real A Body sender and have it repaired. It will be costly but your satisfaction will be MUCH greater.
Lets say you get a usable used one for 75.00, then pay 200 to have it refurbished. You are in 275.00 and have a gauge that will be very accurate.
Now lets say you have already spent 50.00 on an aftermarket sender, then another 50 on a different aftermarket sender, both provide the same inaccurate level so you buy a meter match 90.00, now you are in it for 190 bucks and your tank MIGHT show a form of accurate.
If you look at the wrightup I did in the post I attached you can see the issue with the aftermarket senders. They are linier vs provide a curve. Our gauges need a curve AND our tanks need a different curve. The A100 tank is a rectangle. 1 inch down = 1 gallon of fuel removed from the tank (just numbers for this example.) Our tank has the spare tire cut out in the top, so the first gallon drops the level by 2 inches, the 2nd by 2 more inches, the 3rd by 2 more inches. Now the level is below the cutout and the tank is basically rectangular. So the next gallon drops the level 1 inch and it goes that way for 5 more gallons. Now the bottom of the tank has a taper so 1 gallon is 1.1 inches then 1.2 inches then 1.3 till it is empty. The shape of the tank REALLY matters.
My numbers are way off but you get the point.
