Maybe I’ll hook it up (outside of the tank) to the dash wire and see what it shows in the gauge before I install it.

I did the same thing and the gauge moved up and down with the float, but when installed with gas in the tank it still reads 2/3-3/4 full when 100% full and reads empty when it actually has 1/3-1/2 tank.

Since you mentioned the reading inaccuracy of the new sender, I checked the new and old sender side by side. You are correct: There is definitely a difference in the heights due to the bend of the float hangers. I adjusted the bends with a pliers so the new float hanger matches the old one. Hopefully it makes the reading more accurate this way.

Before and after (full and empty positions)

Success! Gas gauge reads correctly. This is the reading after I put in 8 gallons. Long day...especially when you have to wait all day for amazon to deliver the lock-ring and O-ring that were missing from the fuel tank sender assembly.
