Following my recent Zetec oil pressure questions... Does anybody know the thread size for the oil temp bung in a Raceline sump?

A post on Fb the other day said it was 1/2bsp.
I plan on ordering one so I can drill and tap it ready for the oil change.

I've seen that on a Westy forum post but I've seen M12 and M14 as well. I think I'll end up ordering 1/4" npt and drill/TSP the plug. I've messaged Raceline as well so if they get back to me I'll update here.

That would be good. I’ve heard there not the quickest with replying.

Raceline got back to me and said drill and tap the big blue (oil finger filter) plug on the front and there's plenty of meat to take whatever sender you have. So I'll go for 1/4npt
