The silicone stuff is a bit too big.  I bought some NOS tubes for the 
cool air from someone, but they were the wrong size.  Too small diameter 
and must have been for something else.  I just used an innertube to make 
up the difference.  You can't really see it in the picture though.  Not 
really the best solution for the cool tubes.

But, the galvanized stuff is a pretty close match to stock.  I just 
wanted to show that it has worked out well.
