Fixed? Fingers Crossed!
Poking around I found a likely spot for the leak, under the tank intake flange. I first tried spraying the area with Home Depot Leak Stop. Didn't work. I then cut a window in the belly pan which supports the tank. I was then able to see a 4" crack extending in both directions of the intake flange. I used some JB Weld Water Weld which claims to stick to "almost anything". We'll see.
While underneath I nicked the copper propane line. Decided it was a good time to put in a T and install a Humphrey propane light while I was at it.
Sail on silver girl. Sail on by. Your time has come to shine.
