This is a good thought. The '75 and up tanks have a rubber bladder in them
originally. So even if the tank rusts through, the gas should not leak.
The usual problem with the bladder is it falls out of shape, so that you
begin to be able to put in less gas, like if you have a 24 gallon tank, you
begin to get no more than 23, then 21, or less.

Check the hoses, they are a common problem.
