 Now to the questions. Why is fuel leaking out these tubes? Can I just cap
 off these fittings? >>

Hello,

No, do not cap off the fittings.  They are made to flow.  Dont put a 
collection container either.  You do not want any gas being pooled up giving 
off fumes.

I think that the reason your carbs are flowing gas is that one of your floats 
has developed a crack.  It isnt floating to the top of the bowl and shutting 
off fuel so it is constantly filling and eventually spilling out.

The cracks are usually so fine that you cannot tell they are cracked.  But 
there will be fuel in them.  I suggest that you order a set of new floats 
from the suppliers.  I think they are around $15.

It is an easy fix too.  Just a few screws and the top comes off.
