I think your choice is a wise one, although I would use the GAS 375 for
a 914 installation, the recirculation results in much higher fuel flows
which has been known to block a GAS125 with very fine rust
particles.(from a jerry can) The mesh is 120 micron (from memory) which
is smaller than the mesh in a "Mr Funnel" filter funnel. Both will stop
water.
Andair told me the Rotax specify filter smaller than 100 mu. and 120 is
the nearest available.
