YEP !!! LOL I thought it was attached to the cap like the engine one ? But now that he showed the picture of the little one I think mine has that too. I have to lift the seat all the way up to get it out.
Darn 4020 has been so trouble free I am forgetting where all this stuff is. I did give ours a "treat" a few years back now ? to new hy-gard and a new filter and checked the screen which was still clean.
