A second layer of physical protection against failure for a fuel line of a vehicle for use with high pressure and cryogenic fuels increases safety. The primary fuel line can be assembled from one or more components. The secondary protection is a single outer sleeve that includes a selectively permeable or impermeable membrane and may be reinforced. The sleeve and enclosed volume can also be used to protect against oxygen liquification in cryogenic applications. A means to detect failure of the primary fuel line and optional means to vent leaking fuel depend on the application. Clamp designs may be used to mount and clamp such assemblies in a vehicle structure.
