Well, I have tried two new gas caps, one that locks and that didn't work, then the one I'm using now which has one thin rubber gasket. I can certainly try to create a thicker make-shift gasket.

I still think your original idea of replacing the filler tube would work. I would need to cut off my existing filler tube, then find a replacement tube and join with the rubber neck hose. I sent your friend an email to see if he has one.

Thanks!
