Is this far enough on? Intructions say "fully seated" but it won't go on any further and I don't want to break the fitting.

Just did the same exact thing yesterday so it is fresh in my head. You really should seat it all the way down. It took me half an hour just to get as far as you are without too much side force on the fitting. Then I found the secret. The tube is very stiff so it won't crush easily so you can use a set of needle nose pliers at a major diagonal angle to maximize the area of tube ABOVE the fitting that is in contact with the plier jaw face and push the tube straight down. Doing that will get the tube all the way down in minutes. If you have more questions on the install pm me ill give you my cell and you can call. Use needle nose with some grip on the jaw face not smooth ones.
