With the sender out and connected electrically, I ohm checked the sender at lowest and highest sweep.
It was real close to what the gauge required.
The tank was close to empty, so I put 2 gallons in the trunk and drove it till I ran out of gas and noted where the needle was.
Pulled the sender back out and tweaked the float arm a little.
Now when it reads empty there’s about 1 gallon left.
Perfect.
