Sorry, I know this is way OT now, but, another reason not to go with that way expensive part. My cheapo build also used a SWIVEL connector. (Pictired, that's tee, to NPT-to-flare adapter, to flare swivel connector. Nylon flare washer in metal to metal flare connection, I just use a lot of gratuitous thread tape.) Minor detail maybe, but handy to make sure everything can be tightened up and still have the gauge positioned conveniently. Back to topic, nice new build Sean, and good to see you maintaining the blog again on occasion. Congrats.
