A fuel delivery unit of a motor vehicle comprises a prefilter arranged inside a swirl pot, said prefilter having a filter element, and at least one connection piece for connecting a supplementary filter element. The at least one connection piece, in its initial condition, is closed, and is opened when the supplementary filter element is attached. The invention allows the fuel delivery unit to be adapted to projected filter surfaces of the prefilter.
