Oil pressure sender thread.

Hello. as per title, does anybody know what size and thread the oil pressure sender unit has for the gauge not the red light?
I need a new one and there are a few different types on eBay for half the price of Wins, but with all different threads etc.
Many thanks.

I just looked at three or 4 pumps and the thread is fine, so I would not have thought BSP. I did not screw a bolt in but it does look like 1/2" UNF
Jag senders can be coarse or fine thread, so I don't know if Rover switched between the two as well.

Beware also the new ones are all over the shop in resistance, I would try to find a working OEM sender.
