Abstract:
1. A fuel delivery unit of a motor vehicle, comprising: a swirl pot; an internal prefilter arranged entirely in the swirl pot and having a filter element having a first filter surface configured to filter fuel flowing into the swirl pot; an additional filter having an additional filter element; and a support for the prefilter having at least one connection, which is closed in an initial state by a one-time breakable seal, configured for installation of the additional filter having a second filter surface such that fuel flows through the additional filter and through the at least one connection, whereby the installation of the additional filter in the swirl pot breaks the one-time breakable seal and increases filter capacity by providing an increased active filter surface so that the prefilter and the additional filter are wholly fluidically in parallel such that the fuel passes through one of the internal prefilter and the additional filter to simultaneously filter the fuel.
