Hi Jeff,

I think the problem with converting an older van is
the lack of barrier hoses.  I never could get a
definitive answer from anyone who has tried it on an
early 80s AC, but I've heard r134 leaks through the
non barrier hoses in a matter of weeks.  The other
question is when did VW start using barrier hoses.  It
may have been as early as 91, which is why 90s
vehicles can be more easily converted to r134.
