Small parts for carbs on 85 vf500f

So...
I started up my bike yesterday to find gas nearly streaming out the
bottom of the carbs. After pulling the carbs and going through all
the seals on the bowls and such I thought I had better take a look at
the o-rings on the rails/fuel tubes. Well the o-rings were fine but
one of the actuall tubes is cracked. It's the little "s" shaped one.
anyway... I've seen lots of sights with jet kits and such but no
where have I seen this small part. Bike bandit has the fiche with a
few of the other parts in stock but not this one. Anyone know
somewhere a guy can find small carb parts for this bike or maybe even
a used carb to steel parts from? Thanks
