This was my problem:
both gas tank senders did not work on my new (old ) 73-23.
When I installed the Howell TBI, I found the tanks had been reworked by the
PO.
Every thing looked good
but
Neither of the senders worked, so I had to check the wiring -- it was ok to
the selector .
Now I had to check the wiring at the senders ----
I could not convince myself to drop the tanks for this, So I went in from
the top (GMC tool ;>)
the wiring was good, the sender was bad.
Now I had to enlarge the hole so I could remove the sender from the top.
this is how it was done

I soldered the connection, but I might change it and put in a bolt later
(you can do that with a cap on the hole in the floor ;>)
Future fuel system upgrades without dropping the tanks:
• Single pickup / sender (no need for 2)
• remove tank selector solenoid
• connect both tanks at drain hole for a single tank. (Jim Bound’s mod)
• Remove tank selector switch on the dash
• Add an in-tank pump (Emery’s mod)
• No more “Mystery Reserve “
• Simplify and improve fuel system (no more vapor lock)
• No more removing the tanks for improvements.
