The high-end tool I was flairing with was sure enough 45*.  I've returned it, and bought a 37* tool.  I re-flaired the lines, and started to torque down the fittings, but took a look at AC43.13 just to make sure I was doing it right.

AC43-13 prescribes a way of safety wiring all the fittings that requires a hole through each nut, but none of the fitting I bought from Aircraft Spruce featured a safety wire hole.  I'm I missing something here?  What's the standard practice of saftey wiring fuel and brake fittings?

-- This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
