Tonight I went out to the hangar to try and finish up the mounting bracket for the fuel flow sensor. I realized early on that if I angled the base slightly (about 15 deg), the hoses would line up much more effectively, so that's what I spent most of the time adjusting.
In the end, it was mostly a matter of getting the positioning correct, and then putting everything together. I'm pleased with the outcome and can now move on to finishing the fuel line plumbing inside the cabin.
