Those filters have to be the trickiest way yet for engineers to cause problems with small equipment. Any trash that gets into a tank when refilling immediately blocks them.
The parts diagram only shows the entire tank for the economical sum of $124.99 on Parts Tree.
The "pencil" style filters are shoved into the tank outlet nipple. There should be a fine separation line that indicated the rim of the filter tube at the end of the fuel nipple. Take some pliers and gently squeeze it a couple of times and it will start to come loose. Once loose, the filter can be pulled out.
Option #2 is to ram a pocket screwdriver or a section of coat hanger wire through it and leave the remains in place. That will let fuel flow for the new line and inline filter.
