Many vans have two filters.  The cheap square palstic box filter before the
pump and the more expensive 'beer can' filter after the pump.  My '85 has
only the pre-pump plastic box filter.  My '81 California Westfalia has both.
  The post pump only filter is a bizarre design.  Upgrading to two is easy.
