When Larry A converted his 91, I wonder if he had to
change hoses. In 93 VW was using barrier hoses,
because 93 EVs used r134. I just wodered if you could
get away without doing this PITA hose change? On my
80 Westy, I shudder to think of what would happen if I
tried to take off the old hoses. Something expensive,
or impossible to replace would undoubtedly break.
