Agreed on the dependability/lack of dependability subject of rubber based "Aeoroquip" lines. I have found the teflon lined hoses more dependable and almost indestructible. An excellent point.
It has about the same life expectancy of tire rubber, plus or minus.
I have also used stainless tubing instead of hose. For one thing, it doesn't wander around like the hoses do.
In support of your warning of using braided hose, it really arrived as use on race cars near major aircraft manufacturers. Some how it fell into some workers "lunch pails" and got through security at check out times?
When used in aircraft, it is required to be replaced at certain intervals and documented. That really should be noted for use on street cars as well.
All rubber based hoses need to be replaced eventually so this really should not be a surprise.
I noticed that Porsche uses hard lines where it seemingly would be a hose application, particularly around the oil coolers.
About 35 years ago I had a friend with a GT40. A real one. He was going "nuts" replacing all of the "Aeroquip" on the car. At the time the cost to buy was in the thousands and he really wasn't a trained mechanic. He was an illustration artist. So many of the little nuances that an experienced mechanic learns were just not in his itinerary.
