"Inside that is likely the remains of your old vacuum tube and the little 
brass bit that slips over
the hose and allows it to seal when the nut goes back on....will make
sense once you get it off."

"Little brass bit that slips over the hose"???  There's supposed to be a 
brass bit in addition to the brass nut that screws onto the crossover 
pipe?

I think you're on to something, slinky.

Perhaps my idle will be nigh perfect once I acquire said brass bit.  Where 
do I sign up?
