do you have any data on braid covered teflon?   I guess I'm not seeing they these are so much better than nylaflow except for the braid cover.   lowish melt temperature and not a sky high burst pressure. ....but I don't have the numbers.

It's good reading.

 

BTW, I use SS braided Teflon hoses in every fuel/oil line.  Certainly in the engine compartment, but also from my wing tanks to the header and thence to the firewall.  So far, there is no life limit to teflon.
