I have posted this before (Dec 2007), but maybe it bears repeating it
again for those who wish to continue using the square pre-filter.  The
filter is and has never been available in clear see-thru.

The size of the larger inlet hose is 11mm (VW N 020 300 1).  I have
used standard 7/16" hose from a FLAPS, but this uncommon hose isn't
really easy to find.  I have gotten away with using 12mm Cloth Braided
Emissions/Vapor Hose (VW N 020 374 1) as the barbs on my pump and the
pre-filter pretty well accomodate the hose and because there is no
pressure to deal with should be quite safe.  Always use clamps of
course. This is what I've run for the past 10 (insert 15) years now.

Now a bonus for you (& other list members) if you choose to use the
factory style square plastic pre-filter like I do on both my 84s:

VW:  133 133 511
Bosch Short: 71013
Bosch Long: 0450901005
Wix: 33274
Fram: G3743
