Those square regulators are obsolete. Get one of these: http://www.van-cafe.com/propane-tank-regulator. I was able to "massage" the lines without cutting and re-flaring.

Subject: Another propane leak!

After getting everything all fixed up over the last few days by replacing
my leaking fill valve and installing a new bleed valve, I smelled a whiff
of propane a few minutes ago. I applied soap spray expecting to see bubbles
coming from somewhere on the new work but that was not the case. The
bubbles are coming from the regulator, right where the tube out of the
shutoff valve enters the square body of the regulator.

This regulator was new from Frank Condelli in 2009, and I was careful not
to disturb it when installing the new stuff. There is always a stone guard
on the tank, so I don't think it got hit unless the propane filler guy
smacked it.

Can this be tightened, or do I need a new regulator?

Thanks,

Jim
