- Storage tank remote line section of the line is promoted.
- the fuel is then pumped through the inner annulus back into the storage tank. This results in a continuous flow in the line, through which an undesirable heating can be avoided.
- a desired fuel supply available so that the refueling process can be started immediately, as soon as the line is connected to the motor vehicle.
- the outer annulus is designed to dissipate the gas volumes displaced during refueling from the motor vehicle tank.
- the displaced, also referred to as "boil-off gases" gaseous volumes can be reliably passed through the outer annular space without an exchange with the fuel supplied to the motor vehicle in the storage container to liquefy them there again.
- a leakage of the gaseous components from the motor vehicle tank in the Environment can be avoided and unwanted environmental pollution can be prevented.
- the outer annular space is provided with a separate inlet opening and a separate outlet opening according to a particularly useful embodiment of the line, so that the return of the boil-off gas can be realized separately from the fuel, but by the same line.

- methods for fiber optic temperature measurement for example, glass fibers are used as sensors for detecting occurring leaks.
- an occurring pressure difference in the outer annulus can be used as an indicator of leakage.
- the annulus between the mandrel and the outer tubing could be thermally insulated by a vacuum. It is also particularly practical if a thermal insulating material is provided in the annular space between the jacket tube and the outer pipeline, which has as an essential component a foam, in particular a polyurethane foam (PUR).
