fuel filter replacement

[HBakr@aol.com]

 Hi all,
 my 70 sq started running funny on the way home tonight, unsteady at idle and
 lotsa hikups upon acceleration. That was about 10 miles after filling up at a
 cheap gas station ( could'nt resist!!). So, it sounds to me like a case of
 bad gas and probably a clogged fuel filter as well. NOW come the questions;
  -when changing the filter, any triks regarding the FI high pressure? or is
it
 like.any other filter change?    
 - where do I get a new filter? are they commonly available from your FLPS?or
 do I have to order it?
 Any thoughts are most appreciated
