A supply system for liquid including a liquid tank and a liquid supply line forming a passage for the liquid from the tank to an outlet of the supply system. The supply line includes at least one part configured to form at least one gas pocket communicating with the passage to take up a change of volume of the liquid in event of freezing. Such a system can be used in a selective catalytic reduction system (SCR).

Process for manufacturing a plastic fuel tank equipped with an internal line by molding a parison using a mold comprising two cavities and a core, comprising the following steps: introducing the parison into the mold cavities; introducing the core inside the parison, said core having first been fitted with the line; closing the mold so that the cavities come into leaktight contact with the core; pressing the parison against the cavities by blowing through the core and/or applying a vacuum behind the cavities; fastening the line to the parison over at least two points using a device attached to the core; opening the mold to withdraw the core; and carrying out the final molding of the parison by blow molding and/or thermoforming, in which the line comprises, between its fastening points, a free length that is capable of coming into contact with the parison and/or with an accessory found thereon when the mold is closed, and wherein during the fastening step, at least one intermediate fastening point is created using a device attached to the core.

Degassing circuit for a liquid tank, including a degassing duct connecting the upper part of the tank to a higher point, close to the upper end of the filling duct, via a section in the form of a syphon and a liquid/gas separating volume provided at its base with a device for purging the liquid phase present in the degassing duct, in which the purging device brings the degassing duct into communication with the filling duct and is combined with a device creating a Venturi effect conducive, when filling, to purging the liquid phase present in the degassing duct.
