I haven't had to work on my ERA's unit, but I've had to fiddle with various tank gage unit over the years to tweak the arm and float where it bottom out just a little off the floor of the tank. Did you look the float over carefully - any chance it's leaking and filling with gas?
I checked the float travel while I had the sender out of the tank. It looked right. I did not check to see if the float was leaking. I'll pull it out again tomorrow and check that.

I wondered if the cork gasket was keeping it from making a good ground so I checked that. With the screws into the tank, the ground was good according to my multi meter.

I wonder if this is the right sender for my gauge. I have the Smith's type 4 (from the Wiring Primer) and it says this gauge needs a 350-40 ohm swing type sender. I pm'd Bob a while back and he said I need the SW sender. So one of them is wrong. I get 125 full -25 empty on my sender.
