This happened whether the fuel was auto 91, avgas100/130 , Jet-A, Jet-B. The Goodyear lines seem to be less affected, most of my lines are USA Gates because they are available locally at the auto & marine places. They dont leak or have any service problems as such, just not as pliable as when new and I tend to replace them if they need to be undone for any reason.

I noticed that the Gates cuts much easier than the Goodyear, so I use the latter on the theory that it would be better able to resist abrasion. Yes, I have noticed that it gets hard after a period of time. That is why I replaced it. To finish the report, I took the short samples out of the gasoline and let them dry out for a couple of days. They both went back to exactly 3" in length.

Generally at least every 2 years. My fuel system is very simple tho and regular replacement isn't too hard to do. Being able to inspect the lines is more important than a lifetime beyond 5 years. If I did have fuel lines in places I couldn't get to easily, I'd go ahead and bite the bullet for aircraft grade lines and fittings for those parts (i.e. aeroquip)....
