Well, the front snorkle is aimed at a hole in the radiator diaphragm, and
gets cold grill air at high pressure. The rear snorkle is aimed at the
firewall and gets turbulent pre-heated engine compartment air. An airtight
connection between the two equalizes the pressure so that each carb is
accessing a comparable "atmosphere". Leaving the center connector off also
defeats the purpose of the long snorkles (whatever that might be -- I
presume increasing the velocity of the intake air).
K&Ns and other "unsilenced" filters solve the problem another way, by being
open all the way around, so don't need to be connected.
I used to have a leaky section of generic aluminized tube for a connection,
then I read somewhere a description of the theory behind the stock
arrangement (to which I am not doing justice). The rubber piece is only like
a $3 part, anyway.
