But, I believe the stainless steel braid covering does provide "some" resistance to flames over say the rubber and thread type hoses which I believe definably need the FireSleeves. The only place I have FireSleeve is on the length of aluminum tubing I have in the secondary fuel rail of my injectors (cut down a stock fuel rail and insert the aluminum tube to get the length needed). I felt aluminum tubing in particular is very susceptible to melting in a fire.
