Made these test ells for my '80G out of 1/8" NPT - 1/4" barb ells:
(The one on top I ruined by getting in a hurry and sanded the 1/8" threads off unevenly and the die cut through as seen in the 5th pic)

Tried the nylon tees and they leaked and I didn't want to use teflon tape in case a piece got into the starter jet:


Used a M8 x 1P die:
