Finn,
I would worry about the structure of the filter.  It has a significant pressure
drop across the element in worst case situations (cold start) and you may
damage the filter structure loading it opposite the way it was intended.
That said, you can cut one apart and make your own appraisal of the
likelihood of explosion or collapse of the filter media when loaded the
wrong way.

I did the same thing on the first pass for my remote filter on my Long EZ.
I caught it relatively early in the process, and had to reroute the lines, some
work, but necessary.  I also marked the fittings and hoses to avoid the
same problem in the future.  I never ran mine backwards, so I have no
experience, and I do use a Fram HP-1 due primarily to the thicker can
to deal with high pressures on cold starts.
