I might be wrong, but it I was under the impression it was a horrid thread, very close to 5/8, also its tapered isnt it?

I had to get an adapter made up to fit some jap guages a few years ago, and after visiting a few machine shops, a mate ended up making the adapter out of the old sensor.

I don't think that the heas is tapered but the addaptor can be.

I had my SPi head tapped 5/8 UNF for the standard temp transmitter.

It fits but bottoms out on the hex, so I think it should have been a tapered thread. I'm expecting a bit of grief getting it to seal but have not ran it yet.

I'm pretty sure that on my head the sender hole has a bottom to it (with a hole for the bulb to poke thru) and is tapped 5/8UNF right down to this point.

'tis indeed 5/8 UNF.
When i made some unions for the vaux motor to take the mini temp sensor, I just used a 5/8 UNF lead/first tap and didn't go through to the parralell section - just stopping on the last part of the taper.
The sender screwed in and sealed without any ptfe or anything.
