I have the &quot;sock&quot; or cartridge oil filter on my 1800 gas. When I took it off I found a &quot;gasket&quot; at the bottom of the sock where the tube is. I also found a similiar &quot;gasket&quot; on the top of the sock around the tube where it sticks out of the sock. Neither gasket came in my new filter kit. I only had an assortment of gaskets that would fit the cartridge base to seal the actual metal can that encloses the filter sock.

The two gaskets seem out of place. I attempted to order replacements but these are not shown seperately, so I'm wondering if they truly belong.

Thanks.
