Abstract
A fuel filler pipe having a dimpled filler neck, wherein the dimples serve to concentrically locate a nozzle end portion of a pump nozzle of a service station fuel pump so as to avoid premature fuel flow shut-off during fueling of the fuel tank of a motor vehicle. The dimpled filler neck is provided with three or more nozzle location dimples in the form of bosses radially protruding relative to an adjacent inner surface of the dimpled filler neck. Preferably, the dimpled filler neck has three or four mutually uniformly spaced nozzle location dimples. The nozzle location dimples are positioned at the engagement zone of the nozzle end portion with respect to the filler neck such as to loosely abut the pump nozzle and thereby ensure concentric alignment of the nozzle end portion with respect to the inner surface of the filler neck.
