The Autolite has 2 vent tubes inside the air cleaner and 1 outside. Why =

The cause of the fuel pumping out has to be fixed first no matter what =

Seems to me that the float bowl must be vented to atmosphere in some =
manner,
for the carb to function. The old Ford carburetors went the simplest =
route
they could, vented right on top of the bowl cover. The very easiest fix =
is
to install one of the small Holley 2 BBL carbs which have the vent =
system
inside the air filter ring area on the top of the carb. Either the 350 =
or
500 cfm versions work well. =20
