Ron, I very much like your implementation but I would add one improvement,
that being quick disconnect fittings to permit removal of whatever filters
are used without flooding the cabin with fuel when the filters need to be
removed for cleaning or replacement.
.and no, I have not neglected to use hose clamps - the above is a simplified
image from a 3D CAD model of my fuel system, not a photo of the actual
hardware.

Hi Bob
""any ideas"? and partly a warning to all concerned.
I have managed to very slightly damage the "thimble" filter at the inlet
side of one of my pumps."
I don't know what your fuel system looks like, but will comment on "when" I
too manage to damage one of my sock filters!
Here is what my fuel systenm looks like:
http://contrails.free.fr/engine_914_fuel_syst_test_en.php
Some ideas:
*Call around to Rotax and Europa businesses and get hold of an old burned
out pump and steal filter
*Buy a new pump and put it in your plane, then install a factory filter very
close coupled to intake of pump and use it as a transfer pump to fill your
plane
*For me, if the filter was just slightly damaged, I would put it in my P1
with good filter in P2. If sock were very damaged and beyond reasonable hold
together function, I would just get rid of sock filter on my P1, but
remember I have an Andair 375 gasculator very short coupled to P1 that has a
much finer mesh filter than factory filter and would accept the small chance
that debris may somehow get into intake of unfiltered P1 between Andair
gasculator and intake of my P1. Different story on my P2 intake, much
greater chance that debris could somehow come from outlet of P1, any one of
the many fittings and hoses and connections, G2 or G2 one way that is
upstream of intake of P2. If P1 quits, I should have a good to go P2
*If your system allows, just put another factory filter very close coupled
to your P1 and put the good sock filter in P2
*Help another Rotax 914 owner clean their sock filter on one of their fuel
pumps, and tell them it is a good thing they descided to check, because it
happens to be damaged (>switch<)!
