In what way ? Ie, reads full all the time, reads empty all the time, random
value, etc.

I'm puzzled by that as well. Does a 77 Spit perhaps have a "low fuel"
indicator or something ? Normally there is only one wire for the gauge, the
circuit is completed to ground through the body of the tank.

That sounds more or less normal, the fluctuation is the action of the
voltage "stabilizer".
