Does anyone know what the threaded fitting that the little black cap covers does? My cap and the green decal are missing and I would like to source. Dealer says you can only get them if you buy the whole reservoir, yikes!

Does anyone have resource for the the little black cap and the green decal?

 

Decal is available as a separate part. # 99331480300
