Do you have a bad sending unit in the tank or is it the gauge in the dash? You state you need a fuel sender then refer to a new gauge under the dash.
68 & 69 fuel sending units in the tank went bad quite often. Its due to a crimped on connection on the unit itself in the tank. Over years, it loses its continuity. Mine went bad, I ordered a new unit and when I pulled the old unit from the tank found it just had a bad connection. So I soldered it together and it worked fine. Put the old unit back in. Now I got a brand new unit on the shelf. I guess everyone should have a spare.
