Got a problem, need help/ gas leak

Edd try to find a new gasket for the sending unit. When I was helping you with it your other new gasket looked like it might have swelled a bit from the gas. The rubber they use now is terrible not to mention the crap gas that we have. I'm sure that your lock ring is not the problem but that seal raises suspicion. If you don't have any luck finding one let me know we have a bunch of odds & ends out in Dad's shop, might be able find something there.
