Abstract
A nozzle inhibitor is adapted to be arranged in a filler neck included in a fuel tank fill tube and is configured to allow only a diesel fuel nozzle having an outer diameter that is greater than a specified minimum diameter to be inserted into the fill tube to a depth sufficient so that a user may dispense diesel fuel from that nozzle into the fill tube. The nozzle inhibitor inhibits insertion of a small-diameter unleaded fuel nozzle into the fill tube, yet allows insertion of a large-diameter diesel fuel nozzle into the fill tube so that only diesel fuel is dispensed into a diesel fuel tank coupled to the fill tube.
