Jim:
Even with stuck floats, as you know the carbs only empty into the cylinders,
not the oiling system. You would have to have very considerable ring gap to
pass that much fuel due to gravity feed with tank full and still be able to
start the car without having a fluid lock that would prevent the motor from
turning over. you can fill up the cylinders with prestone/water and have it
set there forever. I suppose gas would dissovle the between piston skirt and
cylinder wall and get down easier than water, however prestone will emulsify
oil too. I am told that 99% of the time it's the pump since it opens right
into the cam gallery. Have you tried taking off the pump and leaving it
connected to the fuel line and in a jar or can to see if fuel seeps out?
Lying in a can on the floor would be about double the pressure it normally
sees and should at least leak a little if it has a problem.

Subject: an invisible leak??
So today I rebuilt the fool pump on the GT6 as per the suggestions of
the kind folks herein. For those with short memories, my motivation
was the discovery that my oil was both more voluminous and thinner
than it should have been. (I can think of no other way for fool to
have gotten into the sump. Surely if I had stuck carb floats I would
have seen big clouds of black smoke.)
To my surprise, on opening up the fool pump I was unable to observe
any alleged leak in the diaphram (diaphragm?). It is possible for
there to have been one or more leak with no visible indication?
Curious.
