A vehicle includes a vehicle body and a vehicle propulsion system. The vehicle propulsion system includes a fuel tank having a nozzle and a tank body. The tank body is made, at least in part, from carbon fiber materials. A method of producing a carbon fiber component for the vehicle is also described.

An assembly for a fluid tank includes a baffle and a fluid transfer line. The baffle includes a first deflecting surface defining a first part of the tank and a second deflecting surface defining a second part of the tank. The fluid transfer line extends from the first part to the second part and is linked to the baffle by a linkage supported by the assembly. The extension of the fluid transfer line in the first part defines a first portion of the fluid transfer line, and the extension of the fluid transfer line in the second part defines a second portion of the fluid transfer line. The linkage allows for simultaneous rotation of the first portion and the second portion of the fluid transfer line towards a surface including one of the deflecting surfaces.
