The Lunkenheimer primer on our Chief is in the need of new nuts to attach the copper primer lines to the inlet and outlet ports.
The spec is:
NPT (ins) Threads per inch (tpi)
1/8 27
Any idea where I can purchase some?
All the best

For what it's worth, the Lunkenheimer primer on the Aeronca seems to be a tractor part. See attached photos. The Rumely Tractors are circa 1910 to 1930 and the primer seems identical to the Aeronca installed one.
The fittings I believe to be standard "compression fittings" available in most general hardware stores (Iron Mongers to you on the other side of the pond...) 1/8inch pipe on one side and the 1/4 inch (I think) compression ring fitting on the other side.
FYI

OK, here's the drawing, it took a bit of digging... Note that it says it's applicable to the 11A, B and C fleets.
The fittings are 1/8 inch pipe and 1/8 inch tube, procured from "Imperial Brass". Here in the States a reasonable A&P should be able to install the hardware store BRASS fittings per the guidance of AC 232-27. I don't know how that works in the UK.
Good luck!

Further digging, FYI
The 1-788 drawing shows the use of a "68F 1/8 X 1/8" fitting. Currently parts are available using this same identification, for example:
https://covalcagroup.com/en/producto/68f-brass-fittings-compression-male-connector/
Since this part identification and production by several companies has survived many decades, it should be an easy argument that the fitting is a "Standard Part" as it seems to be produced to a recognized international standard (the link takes you to a company in Panama.) and can be installed per the guidance offered in AC21-29.
