For a klutz, you've got it nailed
I ran the top tube from the T fitting up to the steering head and added a small fuel filter I had lying about at that end. Seat base, or airbox top level water crossings have been negotiated to date OK.
At the bottom ends of any vent lines, the idea is to cut the end diagonally and split them for say 15 mm. This reduces the possibility of them clogging up with stuff.
Does the T eventing make a difference? Dunno, but its easy to do, and has worked for me on other bikes, albeit with different carbs.
