Y'all are going to join me in a Homer Simpson forehead slap - DOH! when I tell you what I figured out on the fuel pump: of course it isn't getting juice, the engine isn't running! The pump heavily resembles that from my 73 vega, and a vega sends voltage during crank and when oil pressure switch is made. So, I checked for voltage while cranking and yes! It's on a relay. So, I'm ordering a vega pump, as the old one is dead.

As for the sending unit, I carefully disassembled it and cleaned contacts with 100 grit sand paper, and it looks like it's going to work.
