???what ? there is no filter on the block. its on the top front next to the generator. just plug the holes and take it off.
Doesnt need one, only 2 lines to filter. Inlet and outlet. Most remote a Bee Hive or Hildabrant. Just move it to where ever you want and make new lines. Pretty simple. Only 60 and later 390 have full flow filters on right side of block around the starter area.
