So since the problem is solved.....

Do all older style fuel tanks (those with larger fill OD pipe) have a
screen on the pickup? I've seen images of cut open tanks showing a
screen on pickup and return.

My newer Brazilian tank doesn't appear to have a screen unless one is
built into the "dish" at bottom of tank?

Images looking inside the tank when new:
