I planned to do that when my previous pump failed in September, but
AeroAdvantage was quoting a shipping date more a month away and
talking as if it could be much longer -- I didn't want my plane to end
up grounded for most of the fall.

Quite so. You probably need to think of it as an upgrade and just replace the
pump preemptively while your old pump is still working. That way you have a
working pump to keep around as a spare. When I got mine a few weeks ago they
were quoting 3 weeks delivery.
