Your reply is absolutely correct. After posting my inquiry I was able to reach mt friend at the shop and he dislosed to me that had since learned that the earlier model grommet was a hexagon shape and was notorious for leaking on the 5 series. He sold me two of the new round style grommets for $5. Thanks for the reply and advice on how to swap it out. I was glad to hear about these grommets and that I might get to avoid buying a new MC.
