Hi David. Yes. Had read of same. Admittedly I'm not overly familiar
with these plastic pipes so don't have an experience based point of
view, but have seen images of pipes with cracks so assumed that was
another fail point.

I guess the question would be:

"to determine if the pipes need replacing sooner than later, can one
use the length, amount, appearance of cracks to determine this?"

I have to be careful not to do too much preemptive work. In my earlier
Vanagon "career" days, I had been known to replace parts before they'd
failed.     ;)
