Structure tubulaire flexible en partie annelée se situant au moins partiellement à l'intérieur du réservoir de carburant, en particulier d'essence ou de diesel, notamment d'essence, d'un véhicule, ladite structure pouvant être au moins partiellement immergée dans ledit réservoir et destinée au transport dudit carburant dans ledit réservoir, ladite structure tubulaire comprenant au moins une couche (1) comprenant une composition comprenant : a. de 39% à 100% en poids, en particulier de 41% à 100% en poids d'au moins un polyamide aliphatique de formule W/Z, b. de 0% à 4% en poids, préférentiellement de 0 à 2% d'au moins un plastifiant, c. de 0% à 20% d'au moins un modifiant choc, d. de 0% à 37% en poids d'au moins un additif, la somme a. + b. + c. + d. étant égale à 100%, à l'exclusion d'une structure de transport de carburant allant du réservoir jusqu'au moteur du véhicule. A partially annulated flexible tubular structure located at least partially inside the fuel tank, of a vehicle, the structure being capable of being at least partially submerged in the tank and being intended for transporting the fuel into the tank, the tubular structure including at least one layer (1) including a composition including: a. between 39% and 100% by weight, in particular between 41% and 100% by weight, of at least one aliphatic polyamide of formula W/Z, b. between 0% and 4% by weight, and preferably between 0 and 2%, of at least one plasticizer, c. between 0% and 20% of at least one impact modifier, d. between 0% and 37% by weight of at least one additive, the sum of a.+b.+c.+d. being equal to 100% of the total weight of the composition, excluding a fuel transport structure running from the tank to the motor of the vehicle.
