This A/C is drawing 3-4 times as much fuel from the left tank as from
the right and it's not crossflowing on the ground, even overnight.

The lack of crossfeed sounds like the cross feed system is the
problem. Is the crossfeed supplied by the fuel selector being set at
both or a separate cross feed pipe? If you've had water sit in a line
for a long time some corrosion may have gunked up the line from the
right tank -I've seen that in ally pipes connected to a valve with
steel and brass parts.
