Hi all,

I need to find out the size (if there is such a thing) of the vacuum
hose on my 87 that connects (get ready for technical jargon) -- the
cylinder thingie at the top/middle of the engine - just to the right of
the distributor cap - to something underneath it.  The cylinder
thingie has three big tube like things also sticking into it.  The
vacuum hose connects to a nipple on the end.

Also - what changes in engine performance would happen if this
hose were worn, cracked, or just plain not attached any more?  It
was off when I opened the engine compartment this morning, not
sure how long it's been that way.  The end that connects to the
cylinder thingie is cracked so probably isn't forming a good seal.

Thanks all!
