It is on the same circuit as the coil...When ign switch is off - no
fuel....

I suspected that might have been the case when you mentioned that you were
new to boats.
I've been advised by someone far more knowledgeable than I that it should
only be powered
if the engine is running .... via oil switch or other sensor ... and not
powered from the
ignition switch only. Unlike a car or truck, on a boat you don't want
the potential of the fuel
pump pouring fuel on a fire.

If carbureted, you also want the bowl overflow to be plumbed back to the
fuel supply line before the pump and not simply dumped into the bilge like
an automotive carb would do.

Just stuff to think about.

The bowl overflow should be handled by the vent tubes. They are J tubes and
dump the extra fuel into the carb throat. If a ford, the engine will still
use all the fuel and keep running as Fords love gas.
