Claim:
A process for manufacturing a plastic fuel tank equipped with an internal line by molding a parison using a mold including two cavities and a core, said process comprising the following steps: 1. introducing the parison into the mold cavities; 2. introducing the core inside the parison, said core having first been fitted with the line; 3. closing the mold so that the cavities come into leaktight contact with the core; 4. pressing the parison against the cavities by blowing through the core and/or applying a vacuum behind the cavities; 5. fastening the line to the parison over at least two points using a device attached to the core; 6. opening the mold to withdraw the core; and 7. carrying out final molding of the parison by blow molding and/or thermoforming, wherein the line includes, between fastening points thereof, 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, wherein, during step (5), at least one intermediate fastening point is created using the device attached to the core, and wherein the line is attached by a clip having a diameter such that, when the line is inserted therein and hangs by gravity, the line is only in contact with one part of an inner surface of the clip.
