wish i saw this to chime in earlier. i always wet new stem grommets by running them under water for a second while the grommet is on the stem, then they just pop right in. either way you took care of yourself so good to hear. on the hose grommet, you should have one but if not don't sweat it, i have stopped using a hose grommet on my KM's for quite sometime. I find that they actually make the hose easier to pop out, so i go bare back on the hose (what she said
hope it all works out but i can send you another hose grommet if you need.
