In general terms, the invention provides a second layer of physical protection against failure for a fuel line (100) of a vehicle (201) for use with high pressure and cryogenic fuels to increase safety. The primary fuel line (100) can be assembled from one or more components. The secondary protection is a single outer sleeve (20) that includes a selectively permeable or impermeable membrane (20A) and may be reinforced. The sleeve and enclosed volume can also be used to protect against oxygen liquification in cryogenic applications. The invention includes means to detect failure of the primary fuel line (100) and optional means to vent leaking fuel (11) dependent on the application. The invention also includes clamp (40) designs to mount and clamp (40) such assemblies in a vehicle structure (200, 201).
