I believe that most hose comes marked with the manufacturing date as part of the periodic 
inked identification along its entire length. There must be a good reason for this, but I've 
never seen any comment in the maker's literature about a lifetime or shelf life. (I can easily 
imagine that the military might make use of it.) My impression is that it ages almost not at 
all if stored in a reasonable fashion (not too hot, no exposure to ozone, etc.)

Engine heat and exposure to gasoline, and all the extra components in there, are what 
seem to do it in over time.
