group purchase of viton vac line?

[Comcast]

I have a type 85, but your sizes were pretty close to what I have.  I used
silicon hose from www.hosetechniques.com they sell "kits" so that you can
get a mixture of the different sizes needed.  They also have about 12 colors
to choose from.  I found that their basic kit was all I needed to replace
the vacuum lines as well as the washer lines.  It was $30 if I recall.  I
have been very satisfied so far.  They seem to care alot about customer
service, they even send you a letter opener(called a "super slitter") and a
cigar guiotine(called a "super cutter") with their logo on it.  At least
check it out, they have a pretty good site.
