Yes, Thanks for the post. I'm going to install the kit also in a couple of months.I spoke with Jim Foster also, about three days ago, and he stated the same timeframe as to you for the new HP10596 kit. He thought a "nut" was being changed, but Eric called me yesterday and stated that the "seals" are being changed to a "poly"-blah-blah-blah. When I said, "so Viton", he said sounds right(??).
I'm do for my first oil change in about 3-4weeks tops, so hoping the new kit arrives asap.
My Fumoto drain valve arrives this Saturday.
PS...I did put the Amazon 217 & 230 O-ring kits on my Wish List just in case.
As stated in the other post above, hopefully they've changed O-rings but at least I'll know to keep an eye on it.
