If you have the access cover in front of the fill tube removed (below the gas cap and master cylinder access hole), you can have a look at the fill tube itself. From what you've described, sounds like it's not a problem down in the tank, but confined to the fill tube. Can you see that it is secured into the top of the tank properly and no other reasons why it might be blocked or pinched or kinked? I don't know what the likelihood of something getting stuck halfway down your fill tube and causing a blockage is as I've never had mine out or looked down through it. Did you have that fill tube off the car when you did your work?
