On the inboard Stromberg, there is, what I think is a vacuum check valve.  It sits in line between a vacuum line coming from the intake manifold and two lines leading to each carb.  It is aluminum, round with a black cap on top held in place with a cotter pin.

On my GT I heard a hissing coming from it and felt a small vacuum from the hole in the black cap on top.  I removed a disassembled it and found that the diaphragm inside was old and torn.  Currently I simply removed it, running the line without the check valve. 

So, here are my questions...  First, is it OK to run without this valve?  The engine seems to operate OK.  And Second, is there a rebuild kit or replacement available?
