Toyota Repair: gas tank neck filler, emission control system, o2 sensors

Question
where can I find a gas fill tube that supplies the gas to tank, I think Its called  the neck filler? Where can I find it other than local dealer, that may be cheaper? Online? Any sites, because Iwas looking it is hard to find. Any help would be great. Thanks Ted

Answer
You didn't include what year/model it is but I'll try anyway, the reason it may be hard to find as a non-oem part is that the filler tube is part of the emission control system of the car, although some emission control related parts are available aftermarket such as O2 sensors most of the other parts are not, another reason is that using non-OEM parts will void the emission control warranty. Your only choice may be to just get the part from the dealer.
