Content-Type: text/plain; charset="us-ascii"
The size of a filter on the outside has little influence on what can be on
the inside. The original pre-pump filter has a lot of filter material
crammed in there designed to handle the flow (liters per minute) that the
fuel pump can move. I doubt a filter designed for the carburetor on that
motor cycle is designed to handle the fuel in its lifetime that the Vanagon
pump moves in an hour. As it loads up and starts to restrict flow you won't
even know because the element will rip away in there somewhere so the fuel
will just continue to flow.

On the subject of fuel pumps, filters, noisy operation, etc.
Here's a handy hint. Golf Tees are good fuel line stoppers for when you
must work around the fuel system. I keep some in my tool box and just push
one into any line that I have to temporarily disconnect.
I installed a large pre-pump filter into my system. It came from a
Triumph motorcycle and is actually larger than the standard VW post pump
filter.. I see no reason to chance getting dirt from the tank or various
filling stations into my fuel pump, so the pre-pump filter makes sense to
me...thought the one VW uses on some models, that seems too small. Find and
install a larger one, keep your FP happy.. Can't hurt.
