What's the mission? Are you fueling an ultralite?


In flight transfer of fuel from aux tank to main header tank in a
Bowers Fly Baby.

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?

electrical system is gel cell. Engine is A75

Thinking about this pump. Half a pound and $35

That one looks usable - about a 1/2 gpm

Looking at it reminded me that windshield washerr motor-pumps are
designed to handle alcohol mixes - the bugaboo of fuel pumps. Might also
be worth a test?
