I used to worry about the "legs' on that gasket coming off and getting sucked into the oiling system, or just messing with the filter holes
(oil flows from the outside of the can thru the media,then thru the center hole back into the motor IIRC), so I would use the gaskets "loose".If all I had was the "spider" I would cut the legs off making a separate big outer, small inner.Always meant to ask Rapid or JohnRR or Andy about that, never did
(so little time, so many issues).Your call,might be fine as-is out of the box.
