But what happens in carbuerated systems? There is a bowl
there
collecting and holding a 1/2 cup of fuel along with the delivery
lines
and the pumps only deliver a few pounds of pressure vs the 10's of
pound
in an injected systems. How do the carbs get away with
it?
Simple, they vent.
The bowl is open to the atmosphere, so any vapor escapes. The only
requirement is that the fuel pump be able to get enough liquid fuel into the
bowl to keep the level correct. It can pump 90% air, and 10% fuel, as long
as that 10% is enough to keep the bowl full.
