Can you just keep the connector an dispensing line on a corny while you store it or is it likely to leak?

should be able to keep it on for sure.
but do this test - connect to CO2 tank, then close the valve to the kegs. Then check pressure 12, 24 hours later. It should be stable. If it's not - check for leaks.
