  There is a screen _in_ the tank at the fuel outlet fitting. I took mine out
  about a year ago and it was COVERED with rusty crud. To clean it, first 
  drain the tank by some means, then remove the nut that holds on the outlet
  tube. The outlet tube comes right off - pull on the things that looks like
  a washer/gasket- the screen is attached to it and should come out. 

  With the rumors that the oxygenators being put in some fuels now are more 
  corrosive, this may become a regular maintenance item on older buses.
