Let me 2nd part of what Ken said.

I replaced the fuel lines in my '84 with the NAPA high pressure stuff
one December.  The following summer I checked it and it was really
brittle.  I then replaced that with Ken's (Vanagain's) fuel line kit and
now, 4 years later, it's still pliable with no leaks or weeps.  I used
the same hose to replace the short pieces on my injectors, too.
