Sorry, I misunderstood you.

As to Phil's tube, Any chemical is likely to out-gas something that can react with the phosphorous so I would not seal it with anything but hot wax. I did see in his photos, that he is correct, it does look like some of the elements are corroding.... Since its corroding in the gun area, I wonder if the leak is down there as well... Like at the metal pinch off...?

Anyway, my original thought still is what I would do, Put it in a box, metal, glass, plastic, heat it to 90 degrees, pull a vacuum for a few days, then seal it. If you find the leak, and its down at the gun, then even better, seal it there after trying to get the moisture out.
