Fuel Tank Removal

I am finally getting to my '66 Barracuda. I brought it home in September from North Idaho. It has been sitting for 10 years with gas in the tank; my guess is between 5 and 10 gallons. I am working on getting the tank out, but am having trouble getting the filler tube out of the tank. Anyone have some tips to help? Thanks. I am attempting to attach a few pictures... If they don't show up, I haven't figured out the process yet.
