Dan, Dave, and Stuart,

I do like the idea of a large clear filter.  I resisted one mostly
because of convenience.  The VW filter has dissimilar sized nipples so
there is no doubt about the direction of fuel flow.  I think I can get
that right, but I still need an adapter to match hose sizes.  That, and
the feeling that it is best to stay with an OEM type filter has stopped
me from making the change.

Small amounts of water is an issue for the rust, but I doubt that there
is enough water to block the filter.  There is not a lot of moisture in
Phoenix. I haven't driven the car in rain for months, and all of the
hoses, grommets, and expansion tanks are fine. But the suggestion of a
large see-thru filter would resolve any questions about water as well
as give an indication of just how much the tank is rusting.

Thanks,
Mike
