I'm not trying to beat this horse to death, but this question has been 
irritating me.

We spent a lot of time discussing how the fuel that is firewall forward 
gets hot and boils, therefore, the fuel had to be routed someplace where 
it could cool.

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?
