First of all, the pump should definitely stop after it fills the carbs. If
you are not spilling fuel out somewhere, I would suspect a faulty diaphragm in
the pump, but that is actually out of my area of expertise. As to the
electrical problems, I strongly suspect two things: 1) the ignitions switch is
faulty, and 2) you have some miswiring.
The headlights and the courtesy light should work with the key on or off, as
should the hazard switch and, I believe, the horns. The fuel pump should only
work when the key is on. The turn signals and the heater should only work
when the key is on. The starter, of course, should only work when the key is
in the start position.

Either the tach is bad or miswired.

My guess is that the mechanical portion of the switch, i.e., the key portion,
is not connected to the electrical portion, i.e., the switch. You might try
taking these two apart and operating the electrical portion with a screwdriver
to see if it is the switch or the mechanical connection that is faulty.
Otherwise, just start tracing wiring, with a schematic in hand, starting with
the ignition switch and working forward, first making sure you have power to
the ignition switch via the brown wire.
Let me know if I can be of further help.
