Spiked my interest again tonight so I decided to confirm the carto was sealing off in the AGR tank, so I taped the holes shut on the Raven, inserted it in the AGR tank and filled with water. The exterior of the carto is sealing, no leaks. Eliminates an issue with the sanding of the small flange that protrudes beyond the diameter of the carto. It's leaking through the 501 connection.
unless you gripped the raven near the slots ..shifting the wick and coil, creating enough of a gap for the liquid to flow through
