The gas cap on this 40T I got is stuck hard in the filler hole. It looks like it's made out of white plastic, so I can't imagine that it's rusted in place. I'm reasonably strong, but I cannot budge it, even with a solid grip. Hosed it down with Kroil, and walked away.
Any thoughts on what's making it stick? I really want to preserve the part, since they aren't so easy to find.
