Abstract

A fuel delivery device having a collecting receptacle disposed inside a storage tank and from which a delivery unit aspirates fuel and delivers it to an engine. A jet pump which delivers the fuel from the storage tank into the collecting receptacle is disposed close to a bottom of the collecting receptacle and feeds fuel into it through an ascending line that extends up into the vicinity of the upper rim of the collecting receptacle. A separate component is disposed on the outside of a peripheral wall of the collecting receptacle. The outside of the peripheral wall and/or the side of the component oriented toward the peripheral wall has an open channel. The component is tightly connected to the peripheral wall to cover the open channel and to form the ascending line. The collecting receptacle and the component can be easily produced along with the open channel and the component can be attached to the collecting receptacle with a minimum of effort.
