Wanted: Source for Fuel Filler Tube

My fuel filler tube that goes from thegas tank filler opening to the gas tank is rusted out. This pipe goes from the side of the body to the gas tank and is the pipe that you put the gas pump nozzle into. There is a rubber boot on the gas tank that this fits into. Where can I buy a new one of these? Preferably not from a dealer as the mark up is more than I can afford. Any ideas? Aftermarket? My car is a 93 Chevy Lumina sedan.
Thanks!

Hi, I have a 95 Lumina and need to replace the filler tube as well. Were you able to figure out where to buy the item or what it is specifically called?

I found this (http://www.carpartsdiscount.com/auto/parts/96/chevrolet/lumina/fuel_lines_hoses/nylon_fuel_repair_line.html?3593=44260), but I'm not exactly sure that that is what I need

I found this (http://autorepair.about.com/od/fixityourself/ss/fueltank_replac_3.htm) also where they call the hose a "fill tube".

Thanks!

Dealer item from any GM dealer.

Purchase one from a southern yard where they don't salt the roads.
