Go ahead and give it a shot (since it's cheap enough), but it looks like

A friend of mine used a marine bilge pump for years to fill his T-18,
AFAIK, he didn't have any problems with it. *This looks like what he was

They've even got an all-aluminum model for about a hundred bucks mo

The manufacturer claims the pumps do not react to gasoline, but do not
recommend them for transferring fuel.

Thanks Ron, I've been wondering where all the marine pumps were
hiding!

These still seem a little large. I once saw a tiny little wobble pump
in a mooney mite that was exactly what I need. No luck sourcing those
however...

That suggests a minimum transfer rate of a pint a minute would be needed
to keep up with the greatest conceivable flow - but a gallon a minute
would do nicely?

Header tank is 16 gal. After that has gone down to 10 the aux fuel
can be sent to it. That allows approximately 2 hours to transfer the
6 aux gallons to the main (allowing for half hour reserve). Not that
I want to do it that slowly. Actually, for optimal CG it would be
nice to send the aux up when the main is down to reserve so that would
require a much faster rate.

Do you have an electrical system? If so how about one of the "clicker" pumps
like the Cherokee uses. They are made in uncertified versions that are quite
cheap. The Ercoupe O-200 engine installation STC uses one of the uncertified
versions to pump from the wing tanks to the header tank.

If you have C-75 or 85 why not fit an engine driven pump?
