74 amx fuel sending unit

The top reading looks to be 11 ohms

The bottom looks to be around 80 ohms.

Going by angle of the camera during photo and 10x must be done with the upper scale going right to left

For small values of resistance that meter will put you in the ball park. Hard to say how much without a second meter, as a confirmation.

Ok...

In the mean time, i think you could easily adjust the 80 ohms at full reading to be 73 or 72, depending on accuracy of th dial on your meter.

Take note of the float placement at Full and Empty.
Slighlty adjust the Empty stop tang inward to lower the resistance down to 73. You will notice the float at Empty is a wee higher than before.

Without undoing the set angle of the bend of the float wire you can hold the bend end with a vice-grip (to keep it from changing its form), and with a pair of pliers placed before the bend, make a slight bend to lower the float a wee bit. Not too much as you will be lowering the float height of Full. You may do a before and after picture of the float height, with a yard stick as the horizontal to show how close the float is to the top of the tank.

If the slight bend does not help after the adjustment of the Empty stop tang, you can undo the adjustment to as it was, and the stop tang's return back to its original position to give you 80 ohms.

Don't know if it makes sense, to try... its a simplified variant to my help thread. Though my help thread was based on tackling a set of unknowns that can be part of the issue and adjusted to assist with correcting.

So your getting 1 ohm or 10 ohms?

Confused as to what I saw on the scales, and what you stated originally.
