The invention relates to a fluid line (1), comprising a pipe (2), which has an inlet-side end segment (3) having a first connector (5) and an outlet-side end segment (4) having a second connector (10), wherein a cavity (17) bounded in the radially inward direction by at least one auxiliary element (16) is formed in the pipe (2). The problem addressed by the invention is that of minimizing the requirements for the suction performance of a pump that is used to convey a liquid through the pipe. This problem is solved in that a volume reduction element (18) is arranged in the cavity (17) at least in the region of the outlet-side end segment (4).
