A method of making a tank out of blown, thermoformed, or rotomolded thermoplastic material, the method comprising the following steps:

Method of manufacturing a tank of thermoplastic material including a portion in relief for mounting an attachment, and a tank manufactured thereby

A fuel tank includes a vessel having a wall, the wall includes at least a first layer forming a hydrocarbon barrier, and a second layer that is more permeable to hydrocarbons than the first layer and is located on an outside of the first layer. The fuel tank also includes an insert defining a passage between an inside of the vessel and an outside thereof. The insert includes a first end overmolded by the wall and a second end opposite to the first end projecting outside the vessel. The wall has a portion extending inside the insert around an opening of the wall, the insert being configured to form at least one region of reduced thickness in the second layer along a diffusion path for hydrocarbons diffusing along the second layer from an edge of the wall adjacent to the opening towards the outside of the vessel.

Fuel tank comprising blown vessel and overmolded insert

Method of making a blown vessel provided with a mouth, an insert for being overmolded by blowing a parison, and a blown vessel including such an overmolded insert
