I used brass stuff available at the local hardware store. Two 5/16"
nipples with 1/8" NPT; 1/8" female-female coupler; thin 3/8" brass
washers. Open up the hole in the washers to fit. The trick is to use
enough/thickness of washers, and/or filing down the coupler a little
bit, so that as the assembly tightens sufficiently, it's also tight on
the bulkhead. Assemble with hardening Permatex, or Permatex Aviation
Form-A-Gasket, or even epoxy adhesive, which is also fuel resistant.
