Subject: Pre pump filter

Hi folks,

One change I did make, during the tank change out, I was having trouble
locating the correct size fuel line for the tank to pump and during the
search a  local vanagon repair shop I recently discovered said he would
recommend putting in a pre filter in addition to the post filter.  He would
not recommend the plastic cube but instead recommended  a WIX 33248.  I put
this in line before the pump.  I felt as the tank is new and as I could get
crud in by accident, the pre filter could only do good.
This filter goes right in the 11 mm line from tank to pump.

As I noted, in an earlier post,  the pump is quiet so no restriction created
by the additional filter.

Also, when I ordered my injectors from Mansispeed, I noticed he also
recommends a pre pump filter for the 86 and later and makes a kit.  This
inline filter seems a easy way to do the same thing.
