Make your own adaptor out of brass plug. Best bore it in a small lathe then tap it.

Hi Wells
Can you update in your profile where you are located
Not sure what engine you have got ....

For my V8 3.9
No aftermarket sender units will fit ... different thread
I installed a (non electric) mechanical pressure gauge & had to find new brass fittings and recut the thread with a Dye / / Take your old sender unit out / go to a shop that sells fittings (Coventry's / Agriculture shop??) Chose one that is close in thread (Metric from memory) & also buy the right Dye (half inch UNF from memory) ... Use your sender to find & compare the match
Install with thread tape, to seal the thread

The reason for cutting the thread on the brass fitting is that you can refit at a later stage (if needed) the "original" sender unit

I did mine in Esperance WA / went to 6 Agriculture shops before i got all my parts
