Selective fuel nozzle inhibiting system

A fuel intake assembly configured to allow a standard diesel nozzle and a high flow diesel nozzle dispense diesel fuel into a diesel fuel tank but prevent a gasoline nozzle from dispensing gasoline into the diesel fuel tank, the fuel intake assembly comprising:

• a main tube defining a fuel channel, said main tube being in fluid communication with a conduit that connects to the fuel tank;
• at least one flapper movably secured within said main tube, said at least one flapper being movable between closed and open positions, said at least one flapper closing said fuel channel in a closed position and opening said fuel channel in the open position;
• and
• a selective nozzle inhibitor that engages said at least one flapper, said selective nozzle inhibitor allowing the standard diesel nozzle having a first diameter to move said at least one flapper into the open position, said selective nozzle inhibitor allowing the high flow diesel nozzle having a second diameter to move said at least one flapper into the open position, wherein the second diameter is greater than the first diameter, and said selective nozzle inhibitor preventing the gasoline nozzle having a third diameter to open said at least one flapper, wherein the third diameter is less than the first diameter.

A fuel intake assembly comprising:

• a main tube defining a fuel channel;
• a web secured within said fuel channel, said web comprising open areas;
• and
• a plurality of pivot arms positioned over said web, each of said plurality of pivot arms comprising an angled beam that is pivotally secured within said main tube, said angled beam integrally connected to a leg, which, in turn, integrally connects to a shelf, said plurality of pivot arms compressively biased together in the closed position through an annular spring,
• wherein each of first and second nozzles, having first and second diameters, respectively, is configured to spread said plurality of pivot arms apart to expose said open areas of said web, wherein the second diameter is greater than the first diameter, and wherein a third nozzle is too small to spread said plurality of pivot arms apart, wherein the third nozzle has a third diameter that is less than the first diameter.
