Fuel Bowl empties when stops!

I have seen this posted before, by other people.
I have always wondered how a bad fuel pump can allow a float bowl to drain. The fuel inlet needle/seat in the carb is higher then the fuel level in the carb.

I have this same problem on my 84 D-100 with a Carter bbd if it sits for more then 2 days, but I have not looked into the reason, yet. My 64 Valiant with a holley 1920 could sit for over a week, and start right up.

It's not possible for the fuel to get sucked out of the bowl/s by drainback.
It is possible the fuel is running from the needle and seat back though.
But even if the fuel ran back it would still have fuel in the bowl to start and run unless it evaporated. (which happens)
An electric pump solves both.

This is a morning cold start with an electric.
