Steve,
I believe you. I also believe John. Stop! - They are both right (but perhaps not in the same year).
John,
Put a gasoline-safe tube on the end of your metal pick-up tube. If your gas tank was cleaned and sealed, maybe you could run the tube to within 1/2" of the bottom?
Where did you get your sender/pickup - I could not find one when I looked for one several years ago. Luckily, I was able to clean up and reuse my old/original(?) formerly non-working pick-up/sender.
