On our 68, the gauge read 3/4 full regardless when we first got it. I removed
the
tank and pulled the sender. It was frozen in place, I sprayed it down with WD
and
gently started to wiggle it back and forth and it did free up and is 5 years
later working fine. The only thing I would do different is use a better
lubricant
than WD. How long had Bugsy sat before you started all this work on him?
