boost gauge nylon tubing

[Smeins, Larry]

Oliver,
In my experience rubber hose should work fine.  The boost gauge I installed
on my truck came with a plastic line, don't know if it was nylon, and one
day after a hard run the boost gauge dropped to zero.  I tracked the problem
to a section of the hose that had melted and collapsed upon itself.  The
section ran close to the turbo, a very hot area, and probably collapsed
during a zero boost period after a high boost and temp period.  I replaced
the original hose with rubber vacuum hose from Autozone two years ago and
have had no problems since.  This application frequently sees 20+ PSI.
