Aeroquip "Firesleeve" in engine compartment over fuel line and oil line to accusump. Ends taped with aeroquip tape. When I bought it, both only come in orange.

I just looked at some of the road racing and aircraft places that carry it. Now they are encouraging the ends to be closed off with clamps. Doing so will meet FAA requirement for fire resistance. Don't know if its "the best" but its pretty darn good. Insulation inside is thick. If you want to reflect more radiant heat, then slide some aluminumish sleeve on top.
