It's only holding an air temp sensor. BTW, you were right about the
thread being M14 1.5. Got a set of taps off Ebay for pennies which did
the job just fine. Only carbon steel, but ok for ally.

Thread the tube, tap the hole?
Or are the taps/dies too small?

It needs to have a reasonable seal which means a flat surface. (the sensor
goes at right angles to the tube to measure the temperature of the air
passing through the tube) And a thread in thin walled tube wouldn't be
satisfactory.
