Even the well known hose brands we have always considered as tops do not stand up to todays fuel.
I can say from experience, the only hose that should be used on any vehicle driven today with the crap fuel we are forced to buy is one that is E-85 rated.
AND, who knows actually how long these will last as well. The Aircraft industry sets a very short lifetime for all rubber products, especially fuel hose.
Just a fact of life.
