Rick;
SS braided hose comes in two types-- a neoprene runner lined hose, generally
used for fuel hoses, etc and Teflon lined hose, generally used for high
pressure applications like brake lines.
The lifetime of each one depends on the temperature it is exposed to and for
how long. I have also experienced leaks from perfectly good looking SS
braided hose; it was because the neoprene liner had deteriorated and cracked
under the SS braid because the line had been routed too close to the
headers.
Teflon hose lasts for a long time unless it is exposed to very high
temperatures, then it too can become stiff and subject to cracking.
Keeping the hose away from heat sources can make a huge difference in hose
lifetime.

About SS braided hose.... how often do you guys change it out? How do you
inspect it?
I have seen perfectly good looking SS hose leak.

We've been inspected six times now, and never had anyone comment on our fuel
line routing. We used stainless braided fuel line inside a steel pipe which
ran along the floor of our 53' Stude inside, on the passenger side. The
pipe was one solid piece, with open ends in the trunk and in front of the
firewall. My guess is that they like to see extra metal covering fuel line
in the plane of the flywheel/clutch.
