Oh, my. I shouldn't get into this, but....

I've been an aircraft mechanic since the Dark Ages.
Some people think aircraft hoses never need to be changed. Some even fly. And every year, several of them settle on freeways around the country with seized engines.

Most aircraft manufacturers I know of recommend that flammable-fluid-carrying hoses be replaced every FIVE years or so. At twenty years, in a high-temp environment, they will break like glass. I know this. I have seen this. Stainless steel braid is pretty, but the braid doesn't hold the liquid in. The liner does.

Teflon-lined hoses will last longer, as long as they are not disturbed. If disturbed, all bets are off.

Dunno much about NASCAR, but have heard those cars are only used a couple of years. Braided hoses will last that long, I suppose.
