1956 JI Case 400 propane leak

[auark]

If the tractor is full it holds fine for a few days the every now and then you can smell propane. Hard to soap as it comes and goes. The vapor valve and liquid valve are off. It takes a month or two and the tank drains. Any ideas?
Thanks

Had leaky valves on my lp 930. Had to replace both.

Thanks. Was this the filler side valves or the turn valves you had to replace. Where were you able to find them.

I have had the square O-ring behind the gauge leak, also had both fill valves leak on my 910B. Frustrating when problems are intermittent.
