Sending unit is loose in the gas tank - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just replaced the gas tank in my '72 C20. The new tank is a Spectra. It fit surprisingly well(had to tweak the neck just a little but I'm told that's just how they are). The sending unit is virtually new(replaced a couple hundred miles ago).
My problem is, when I install my nearly new sending unit(with new o ring) in my new tank, it is still loose even after the lock ring is in place. It fit just right for the short time it was in the old tank.
What gives?
Is there anything I can do other than hopefully finding a fatter o-ring?
