However, the resin has stuck it into place, which makes it hard to remove.

The flat metal, welded seam tanks are the replacement tanks. Made in Canada, they had filler necks that didn't accept the original gas caps very well. Underneath the tanks, in that deep well, was the perfect dirt and moisture trap. The tanks generally rusted from underneath. Reminds me that I need to remove mine, slean out the mudwell, and paint the well and bottom of the tank with something like tremclad or POR-15.
