From an old keg I no longer use: (hope this helps)

Very helpful indeed. Thanks.
That looks to be 22-3/4" +/-. My 2.5 gallon keg measures about 12". So, 10-3/4" would be about right for the hose length, which is a smidge longer than my initial guess. I'm thankful I stopped cutting at 12" until I got some evidence.
I may take an extra 1/2" off tonight and see how she floats, still trying to be cautious of going too far, just in case.
**Edit**
My original reply above makes absolutely no sense at all, but I'll leave it there so as to nail my foolishness on the door.

The original hose shipped with the CBDS was 18" and was supposedly designed for 5gal kegs. If (a big IF) a standard 5gal keg has an interior height of 22-3/4" then that means the hose should be 4-3/4" shorter than the keg interior. Hmm. That would mean for my 12" high 2.5 gal keg, the hose should be only 7-1/4" long.

Well maybe, but that seems uncomfortably short to me.
I'm going back to the "cut a little at a time" method. I'll get there eventually.
