I think most people get barbed fittings and a tee from the hardware store.

You can just bring the hose with you and match up the size at the store.

Parts I used -

Brass T with 1/4" NPT ports
2 1/4" NPT hose barbs with (I think) 5/16" hose barbs. The hose barbs were just the size that fit on the TB hoses - I just eyeballed it

. The only other sizes were obviously too big or too small.
1/4" NPT to 1/8" NPT adapter/bushing.

As you can see in the pics, teflon tape up the fittings and screw it together. I used the 1/4" NPT to 1/8" NPT adapter to space the water temp sensor up and away. If I would have used a 1/8" NPT brass tee, the tip of the sensor would have interfered with the opposite side of the tee - best case it would have touched the brass and possibly give a false reading, worst case it wouldn't screw in enough to make a watertight seal at the threads.

BTW, all the Japanese temp sensors are 1/8" NPT - I'm not sure what Autometer is, I'm guessing 3/8" NPT. You're on your own there
