Bob,
My book says 1.5 to 2.5 psi. Is that the "correct" yours is running at?
Other than that possibility, sounds like you have them covered. Could there
be an issue internally with the carbs that is allowing gas out the float bowl
overflows at too low a pressure? If so you may be able to check by routing
the overflows to a temporary catch can. At least that would identify where
the smell is coming from.
Of course, this is an uneducated guess by a guy who has generally considered
carbs and trannys as magic boxes where mysteries of the universe are
performed... Well maybe I'm not quite that bad, but I somehow have never
spent much time working with the innards of either.

OK Folks I am out of ideas.
At freeway speeds I can smell gas but when I stop it is not apparent
where the gas is coming from. It seems like it has to be the float
bowl overflows since all the lines are good and if they are leaking
speed should not make any difference. For some years I have been
fighting grit from the gas tank - - powder coater blasted it with out
taping the openings after the tank had been cleaned. Ran lots of
paint thinner through the tank before reinstalling, added two in line
fuel filters and grit still got through. After five sets of filters
and float bowl jets and needles I thought the problem had been licked
- - no more over flow at idle. The pump pressure is also correct,
check last week. But still smell gas at freeway speeds.
Thoughts???
Thanks
