I used the wider gasket that came with the cap. I tried the original gasket off the OEM cap but it does not fit as flush to the new cap. Others have said that either gasket in the kit works. The brass item left of the N light is the daylight sensor for a Kissan headlight modulator. I have been very happy with the positioning for that as well.
