The only braided line I'd trust for more than 4-5 years is the Teflon lined hose . ....It's impervious to almost anything, I have it for my main fuel line on my Willys for over 20 years.
All the rubber hose gets hard after 4-5 years and if you take a knife and scrape the inside it will flake off. .......Just what you want getting into your carb , or oil system.
The lightweight cloth braided stuff goes away even quicker.
Think about the hose ends as well .... fuel line fittings are some of the most used / removed of all fittings . the ends do wear out from constant use .
