It's been interesting seeing what people come up with, but one thing that
I've learned the hard way in various design projects (TD landing gear, BRS
installation, etc) is keep it simple as possible, and if possible keep the
quality of the bits as high as possible. I've yet to see anything that
really convinces me that it's possible to better (in order) 2 tank outlets,
1 tap, 1 aux fuel pump (either by-pass type, or with a one way valve in
parallel) I gascolator, (then engine fuel pump) and a return bleed to the
reserve side.
All the problems seem to come from (1) not making sure that the fuel system
is clean initially, and (2) from not making sure that the fuel is clean when
it goes into the aeroplane.
