Almost certainly bu see 2.

Yes. All pumps should have a ground connection. It is quite possible for
it to be grounded without one, but only via several metal-to-metal fixings
(like the fuel pipe!) that weren't intended to provide an electrical path.

101? Room 101 in George Orwell's 1984 was where people were confronted with
their worst nightmares. Electronic ignition on its own is unlikely to be
giving poor economy unless you have serious mis-firing, more likely it is
due to poorly adusted carbs and/or timing, valves or some other cause. It
is not unusual to disable vacuum advance with operformance distributors, and
the OE electronic ignition was like this.
