Abstract:
1. A process for manufacturing a plastic fuel tank equipped with a pump, by molding a tubular parison cut into two sheets via a mold comprising two cavities and a core, said process comprising the following steps: step 1. the parison is introduced into the mold cavities; step 2. the core is introduced inside the parison, said core having first been fitted with a swirl pot comprising a housing for the pump; step 3. the mold is closed so that the cavities come into leaktight contact with the core; step 4. the parison is pressed against the cavities by blowing through the core and/or applying a vacuum behind the cavities; step 5. using a device firmly attached to the core, the swirl pot is fastened to the parison; step 6. the mold is opened to withdraw the core; step 7. the final molding of the parison is carried out by blow molding and/or thermoforming; and step 8. the tank is demolded, and through an opening in the latter, the pump is mounted in the housing of the swirl pot, wherein the mounting of the pump is achieved by way of an intermediate part, the external shape of which is standard, fixed and complementary to that of the housing, and the internal shape of which is adapted to the pump, wherein said intermediate part is able to be mounted on and demounted from the housing as it is, through a quick connect type connection, without having to alter its overall geometry, wherein the intermediate part comprises a pump holder and a cover, and wherein the pump holder is plugged into the housing using a spherical linkage and a lever arm with a clip.
