Dave, this is just My opinion.  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.
