Fuel gauge on 30u Plymouth is a very intrequette piece of equipment , at least they are made so that they can be pulled apart,not like some modern day gauges.
The needle in gauge was not moving freely so had to ajust pivot points by bending brass support. also had to reverse wires as I am using alternater for time being this is because of positve to negative ground ,now gauge is reading smidgen under quarter of tank fuel when I dipped tank smidgen over 1/4.
sender in tank was seized when I purchased car last june Is now working !
You sure are handy, great job.
